Top 3 Picks for Best Bench Function Signal Generators

Best Bench Function Signal Generators in 2026

1. Rigol DG1022Z - Best Overall Bench Function Generator

The Rigol DG1022Z has been my go-to bench generator for over a year now, and it continues to impress. Right out of the box, the build quality stands out. This is not a flimsy plastic unit that slides around your bench. At 7.7 pounds, it sits firmly in place, which matters more than you might think when you are adjusting knobs mid-test.

The dual-channel output with 14-bit vertical resolution delivers clean, stable waveforms across the full 25MHz range. I have used it for everything from basic sine wave testing to more complex arbitrary waveform generation, and the signal fidelity has been consistently reliable. The 2Mpts arbitrary wave length gives you plenty of room for custom signals.

What I appreciate most is the straightforward user interface. Unlike some generators that bury functions in nested menus, the DG1022Z puts everything within easy reach. You can set up a test in seconds without reaching for the manual. The only thing I would improve is the fan noise, which can be noticeable in a quiet lab environment.

Who Should Buy This

This is the right choice if you want a professional-grade bench function generator from a trusted brand. It suits engineers and serious hobbyists who need reliable dual-channel output without paying Tektronix or Keysight prices. The Rigol DG1022Z delivers where it counts: signal accuracy and day-to-day usability.

Who Should Look Elsewhere

If you need higher bandwidth above 25MHz, you will want to step up to a different model. Likewise, if your budget is tight and you only need basic waveform generation, some of the budget options in this list offer more features per dollar.

2. Seesii 80MHz Dual Channel Signal Generator - Best Value

The Seesii 80MHz dual channel signal generator punches well above its weight class. When I first set it up, I was skeptical about the 80MHz claim at this price point. After testing with my oscilloscope, I can confirm it holds up. The sine wave output stays clean well into the higher frequency ranges, which is more than I can say for some competitors.

The 275MSa/s sample rate with 14-bit resolution gives you solid signal definition. With 160+ built-in arbitrary waveforms, you have a library of options without needing to program anything custom. The phase difference adjustment from 0 to 359.99 degrees is a nice touch for dual-channel phase-related testing.

One feature I genuinely use all the time is the mobile app control. Being able to adjust parameters from my phone while watching the oscilloscope across the bench is surprisingly handy. The PC software works well too for creating and downloading custom arbitrary waveforms. At under 3 pounds, it is light enough to move between benches without any hassle.

Who Should Buy This

If you want the most frequency bandwidth per dollar, this is your pick. The 80MHz range covers audio testing, basic RF work, and most hobbyist needs. The app control and dual-channel output make it a strong value proposition for anyone building out a lab bench on a budget.

Who Should Look Elsewhere

If you need very high signal purity at maximum frequency or professional-grade documentation and support, the premium brands like Rigol offer better long-term reliability. Some users may also find the lightweight construction less confidence-inspiring than heavier bench units.

3. OWON DGE2070 70MHz Dual Channel Generator - Best Portable Bench Unit

The OWON DGE2070 caught my attention with its ultra-thin profile and impressive spec sheet. At just 1.85 pounds and measuring under 3 inches deep, it takes up minimal bench space while still delivering 70MHz of bandwidth across two independent channels. The 300MSa/s sample rate is the highest in this price range, which translates to cleaner signal reproduction.

The 3.6-inch LCD display is crisp and readable from different angles. I found the menu system intuitive, with modulation modes including AM, FM, PM, and FSK accessible without diving through layers of menus. The 150 built-in arbitrary waveforms cover most common test scenarios. It even includes test leads in the box, which is a nice touch that saves you an immediate accessory purchase.

During testing, the signal quality was good at lower and mid frequencies. However, I noticed the square wave starts looking more like a sine wave as you approach 20MHz. This is a known limitation that several users have reported. For most bench work below that threshold, the DGE2070 performs admirably and the sweep and burst functions add genuine value.

Who Should Buy This

This generator is ideal for users who need portability without sacrificing too much capability. Field engineers, students who transport their gear, and anyone with limited bench space will appreciate the slim design and comprehensive feature set.

Who Should Look Elsewhere

If your work demands precision square waves at high frequencies or you need laboratory-grade accuracy, look at the Rigol DG1022Z instead. The high-frequency signal degradation is a real limitation for certain applications.

4. OWON DGE1030 30MHz Waveform Generator - Best Entry-Level Option

The OWON DGE1030 is the little sibling of the DGE2070, and it serves as an excellent entry point into bench function generators. I tested this unit over several weeks of light bench work, and its straightforward interface made it one of the easiest generators to pick up and use. There is no learning curve worth mentioning.

With 30MHz of bandwidth, 125MSa/s sampling, and 160 built-in arbitrary waveforms, you get a remarkably complete feature set. The AM, FM, PM, and FSK modulation modes are all present. Sweep and burst functions work as expected. The SCPI-compatible PC remote control is handy if you want to automate measurements.

The main trade-off is the physical build. At just 2.12 pounds, the DGE1030 can shift around when you press buttons firmly. One reviewer confirmed that the output voltage reading doubles the actual value, which is something to be aware of. There is also no USB stick connection for loading arbitrary waveforms, which limits customization options compared to competitors.

Who Should Buy This

Students and hobbyists just starting out will find this generator hits the sweet spot of capability and affordability. If your work stays mostly in the audio frequency range and below 15MHz for square waves, the DGE1030 gives you everything you need without paying for bandwidth you will not use.

Who Should Look Elsewhere

If you need verified voltage accuracy or plan to work extensively with square waves above 15MHz, consider the Seesii 80MHz or Koolertron 60MHz models instead. The voltage reading discrepancy is a concern for precision work.

5. Koolertron 80MHz DDS Signal Generator - Best App-Controlled Generator

The Koolertron 80MHz DDS generator brings Bluetooth connectivity to the bench, and that feature alone makes it stand out in this price range. The mobile app connects quickly and lets you adjust frequency, amplitude, and waveform type from across the room. I found myself using the app more than the front panel after the first day.

Under the hood, the FPGA integrated circuit and high-speed MCU deliver stable dual-channel output at 275MSa/s. The 8192-point waveform length is generous for custom arbitrary waveforms, and the included PC software lets you draw and download your own waveforms. With 100 storage groups, you can save instrument states for different test setups.

The build quality is decent for the price, though the lack of a numeric keypad means you rely on arrow keys or the app for frequency input. Some users have reported firmware update difficulties and unresponsive customer service, which is worth noting if you value post-purchase support. The clip leads that come included have a sliding plastic insulator that makes them harder to open than standard clips.

Who Should Buy This

Anyone who values wireless control and a wide 80MHz frequency range will appreciate this generator. It works well from audio frequencies right up through basic RF testing, making it versatile for home labs and light professional use.

Who Should Look Elsewhere

If you need reliable customer support or plan to do firmware updates, the experiences reported by other users suggest this could be frustrating. The Seesii 80MHz model offers similar specs with slightly better user feedback on reliability.

6. Koolertron 60MHz DDS Signal Generator - Most Popular Budget Choice

With over 300 reviews, the Koolertron 60MHz is one of the most popular budget signal generators on the market. I wanted to see if the hype was justified. After weeks of testing, I can say it delivers where it matters: basic waveform generation across a wide 60MHz range at a fraction of what big-name brands charge.

The dual-channel DDS output with 200MSa/s sampling handles sine, square, triangle, and arbitrary waveforms. Signal quality is clean and accurate at lower and mid frequencies. The display is bright and readable, and the button layout makes sense after a few minutes of use. You get 99 storage groups for saving setups, which is plenty for most users.

There are compromises, as you would expect at this price. The 2.2-pound weight means it slides around when you press buttons. At the highest frequencies, the amplitude accuracy drops and some users report RFI issues due to the plastic case providing poor shielding. The arrow-key frequency adjustment gets tedious when you need precise values.

Who Should Buy This

Hobbyists, students, and anyone building a first or second lab bench will get tremendous value from this generator. The 60MHz range covers audio, basic RF, and most educational lab experiments. It is a practical choice that hundreds of users have validated.

Who Should Look Elsewhere

Professional engineers who need consistent accuracy at maximum frequency or robust RFI shielding should look at the Rigol DG1022Z. If you need app control, the Koolertron 80MHz or Seesii models are better options.

7. Seesii 60MHz DDS Function Generator - Best for Audio Testing

The Seesii 60MHz shares a platform with the Koolertron units but adds its own character. I spent time using it specifically for audio circuit testing, and it excels in that role. The sine waves are clean through the audio band, and the precision stays within the stated 0.1% specification based on my measurements.

Dual-channel output with independent parameter settings per channel is a standout feature. You can set different frequencies, amplitudes, and waveforms on each channel simultaneously. The 60 positions for user-defined waveforms and 99 groups of instrument state storage give you plenty of room for saving test configurations.

The control panel uses a combination of buttons and a rotary encoder that feels satisfying to use. Users on the EEVBlog forums specifically recommend this type of Seesii generator for audio frequency work and vintage equipment repair. My experience confirms that, with the caveat that the internal power supply can introduce some noise into sensitive measurements.

Who Should Buy This

Audio engineers, vintage equipment restorers, and anyone doing frequency response testing in the audio range will find this generator well-suited to their needs. The precision and dual-channel independence make it particularly useful for stereo and multi-channel audio work.

Who Should Look Elsewhere

If you need sweep synchronization for automated measurements or a generator with proven long-term reliability, the power button issues some users report and the lack of a sweep sync signal may be dealbreakers. Consider the Rigol DG1022Z for more demanding applications.

8. Koolertron 15MHz DDS Signal Generator - Amazon Best Seller

With 471 reviews, the Koolertron 15MHz is the most reviewed signal generator in its category on Amazon. That kind of track record means something. I tested it alongside higher-frequency models and found that within its 15MHz range, it performs just as well as units costing significantly more.

The dual-channel DDS output uses the same FPGA-plus-MCU architecture as the rest of the Koolertron lineup. Sine waves are clean, square waves are sharp, and the 14-bit resolution provides adequate detail for most test scenarios. The display is well-lit and the menu system is intuitive even without reading the manual.

The main issue is the physical construction. At just over 2 pounds, this unit moves around on the bench whenever you interact with it. The included BNC cables and adapters have quality concerns, with some users reporting noise that was traced back to the cables rather than the generator itself. The arbitrary waveform creation software has a steep learning curve with limited documentation.

Who Should Buy This

Anyone primarily working with audio frequencies, sensor simulation, or basic circuit testing will find this generator perfectly adequate. The 15MHz ceiling is sufficient for a huge range of hobbyist and educational applications, and the massive number of positive reviews speaks to its reliability.

Who Should Look Elsewhere

If you need frequencies above 15MHz or plan to create complex arbitrary waveforms, the software limitations and bandwidth ceiling will frustrate you. Step up to the Koolertron 60MHz or the Seesii 80MHz models for more headroom.

9. Seesii 15MHz DDS Function Generator - Best for Beginners

The Seesii 15MHz is the younger sibling of the 60MHz model, sharing the same FPGA and MCU architecture in a more affordable package. I found it works well for its intended purpose: basic waveform generation for audio circuits, sensor testing, and educational labs. The 2.4-inch LCD is smaller than the displays on higher-end models but still perfectly readable.

The control panel uses the familiar rotary adjustment knob that makes frequency tuning feel natural. External trigger functionality works as expected, which is important if you are synchronizing the generator with other test equipment. The 99 storage groups and 60 user-defined waveform positions give you room to grow.

The compromises are familiar at this price point. The unit weighs barely over 2 pounds and has a tendency to slide around the bench. Some users have reported voltage accuracy issues at higher frequencies, and there are isolated complaints about power button reliability. For the price, these are acceptable trade-offs, but they are worth knowing about before you buy.

Who Should Buy This

Beginners and students who are just learning about signal generation will find this an approachable and affordable first generator. The straightforward interface and adequate feature set make it a good learning tool without overwhelming new users.

Who Should Look Elsewhere

If you need guaranteed voltage accuracy or plan to work at frequencies near the 15MHz ceiling, spend a bit more for the Koolertron 60MHz model. The reliability concerns, while not universal, are worth avoiding if your work depends on consistent performance.

10. TestHelper TH-71B Handheld Signal Generator - Best Field Calibrator

The TestHelper TH-71B is not a traditional bench function generator, but it earns its place on this list as the best handheld process calibrator. I have used it in industrial settings for 4-20mA loop calibration, and it consistently delivers results that compare well against units costing five times as much. Users on industrial forums frequently compare it to the Fluke 707, and the consensus is that it does 90% of the same work at a fraction of the cost.

Beyond voltage and current sourcing, it supports eight thermocouple types (K, E, J, T, B, R, S, N) for temperature simulation. The 24V loop supply eliminates the need for a separate power source when testing loop-powered instruments. The backlit display is genuinely excellent, easily readable in dim plant environments.

The main drawbacks are practical. The included test leads are low quality and I recommend replacing them immediately. The unit can tip over on its built-in stand if you are not careful with cable routing. Thermocouple readings take time to settle, which slows down calibration workflows. But at this price point, these are minor inconveniences rather than dealbreakers.

Who Should Buy This

Industrial technicians, PLC programmers, and instrumentation specialists who need a portable calibration tool will find the TH-71B invaluable. If you work with 4-20mA loops, thermocouples, or process control systems in the field, this is a must-have tool.

Who Should Look Elsewhere

If you need a bench-top waveform generator for electronics design and testing, this is the wrong tool. The TH-71B is a process calibrator, not a frequency generator. Look at the Rigol DG1022Z or OWON models for traditional bench work.

11. Riiai SG003A 4-20mA Signal Generator - Best for PLC Testing

The Riiai SG003A is a compact signal generator designed specifically for PLC testing and process control work. I carried this unit around for two weeks of field testing, and the battery life is genuinely impressive. The 3000mAh internal battery delivers close to the advertised 26 hours of continuous use, which means you can go multiple days between charges.

The 2.4-inch color LCD is a step up from monochrome displays found on similar tools. You can view both input measurements and output signals simultaneously, which is incredibly useful when you are injecting a signal into a PLC input while monitoring the response. The programmable auto mode with monotonic rise, fall, and cycle options automates routine calibration procedures.

Where the SG003A falls short is documentation and interface design. The manual reads like a poor translation, and the menu system requires trial and error to navigate efficiently. The mA output at 20mA reads approximately 19.8mA on a calibrated meter, which is close but worth knowing about. Some on-screen text has typos that suggest rushed quality control on the firmware side.

Who Should Buy This

PLC technicians and automation engineers who need a reliable, portable signal source for field work will get great value from the SG003A. The long battery life and dual display capability make it particularly useful for commissioning and troubleshooting control systems.

Who Should Look Elsewhere

If you need laboratory-grade accuracy or a waveform generator for electronics design, this is not the right tool. The slightly low mA output and confusing interface make it unsuitable for precision calibration work where every decimal matters.

12. TKXEC Adjustable Signal Generator - Best PWM Simulator

The TKXEC Adjustable Signal Generator is a pocket-sized multi-function tool that combines voltage sourcing, current sourcing, and PWM generation. I was surprised by how capable this little device is for LED testing, PWM motor control simulation, and panel meter calibration. The short circuit and reverse connection protection gives peace of mind during field use.

The built-in 1500mAh lithium battery charges via USB and provides several hours of use. Voltage output goes up to 12V with 0.03V accuracy, and current output covers the standard 4-20mA range with 0.05mA accuracy. The PWM output from 1 to 150kHz with adjustable duty cycle is the standout feature that sets this apart from basic analog simulators.

The user interface is where this device shows its budget origins. Navigation between modes is not intuitive, and the buttons lack the tactile feedback you would want in a professional tool. At 7.4 ounces, it truly fits in a pocket, but the small size means you sacrifice the larger display and dedicated knobs of bench generators.

Who Should Buy This

Technicians who need PWM signal generation for LED testing, motor control debugging, or PLC panel testing will find this tool genuinely useful. Its portability and rechargeable battery make it a great addition to a field service kit.

Who Should Look Elsewhere

If you need high-frequency waveform generation above 150kHz or complex arbitrary waveform capabilities, this device will not meet your needs. It is a simulator, not a full function generator. Look at the Koolertron or OWON bench models instead.

13. EC Buying XR2206 DIY Function Generator Kit - Best DIY Option

The EC Buying XR2206 DIY kit is exactly what it sounds like: a function generator you build yourself. I assembled one over a weekend, and the experience was genuinely enjoyable. If you are learning electronics or want to practice soldering, this kit serves double duty as both a learning project and a usable piece of test equipment.

Once assembled, it generates sine, triangle, and square waves from 1Hz to 1MHz with coarse and fine tuning. The power supply accepts 9-12V DC or a 9V battery, making it flexible for bench or portable use. The components are good quality and the PCB layout is straightforward to follow.

The caveats are real, though. Several users report that the included case does not fit properly, so you may need to modify it or use the board bare. The amplitude knob functions in reverse on some units, which is confusing until you get used to it. There are minor PCB flaws on some boards, though most are cosmetic rather than functional.

Who Should Buy This

Electronics students, hobbyists learning soldering, and anyone who enjoys building their own test equipment will find this kit rewarding. It is also a great gift for someone getting started in electronics who wants a hands-on project.

Who Should Look Elsewhere

If you need a reliable, ready-to-use function generator for actual circuit testing, skip this kit. The assembly quirks and quality inconsistencies mean it is better suited as a learning tool than a daily driver on your bench.

14. Seesii FG-200 Portable DDS Signal Generator - Best Pocket Generator

The Seesii FG-200 is about the size of a deck of cards and weighs just 12.3 ounces. I tossed it in my toolkit and forgot it was there until I needed a quick signal source for an oscilloscope calibration in the field. For that purpose, it works surprisingly well. The DDS technology delivers cleaner waveforms than I expected from something this small.

The frequency range covers 1Hz to 500kHz with sine, square, triangle, and sawtooth waveforms. The built-in 7.83Hz Schumann resonator is an unusual feature that some users appreciate for relaxation purposes, though from a test equipment perspective, it is the frequency accuracy and stability that matter more. The switchable filter helps clean up sine and pulse outputs.

The biggest limitation is the lack of a built-in battery. You need the included AC/DC adapter or an external battery pack to power it, which somewhat undermines the portability. The membrane buttons require firm presses and setting precise frequencies is tedious with the limited input options. At higher frequencies, waveform distortion becomes noticeable.

Who Should Buy This

Anyone who needs an ultraportable signal source for quick tests, ham radio antenna work, or occasional oscilloscope calibration will find the FG-200 handy. It is also a good option if you want to try out signal generation without committing to a full bench unit.

Who Should Look Elsewhere

If you need anything above 500kHz, dual-channel output, or precise frequency control, this pocket generator will frustrate you. It is a supplementary tool, not a replacement for a proper bench generator.

15. TKXEC 500kHz DDS Signal Generator - Best Ultra-Budget Pick

The TKXEC 500kHz DDS generator is the most affordable complete signal generator on this list. For the price, you get a surprisingly capable little unit with 15 waveform types including sinusoidal, square, triangle, sawtooth, ECG, exponential rise and fall, Lorentz pulse, and Gaussian pulse. That variety is impressive at any price point.

The frequency resolution goes down to 0.01Hz, which allows for very fine-tuned signal generation in the lower ranges. The included transmitting antenna for the 7.83Hz Schumann resonance feature is a nice inclusion. The setup is straightforward, and the compact size makes it easy to store or transport.

Durability is the main concern. Multiple users report units failing within two months of purchase, often related to power connection issues. The build quality is clearly budget-oriented, and there is no getting around that fact. This is a tool for occasional use and learning, not for a professional bench that needs reliable daily performance.

Who Should Buy This

Students, absolute beginners, and anyone curious about signal generation who wants to spend the minimum to get started will find this a reasonable first step. The variety of waveform types provides genuine learning opportunities even at this low price.

Who Should Look Elsewhere

Anyone who needs reliable long-term performance or plans to use their generator regularly should invest more in a Koolertron, OWON, or Rigol model. The durability concerns are significant enough that I cannot recommend this for anything beyond light, occasional use.

How to Choose the Right Bench Function Signal Generator

Choosing a bench function signal generator comes down to matching the specifications to your actual needs. I have seen too many people overspend on bandwidth they never use or underspend on a generator that cannot handle their daily work. Here is what actually matters when making your decision.

Bandwidth and Frequency Range

Bandwidth is the most important specification on any function generator. It determines the highest frequency sine wave the unit can produce cleanly. For audio work, you need at least 20kHz. For general electronics testing, 15 to 30MHz covers most use cases. RF work demands 60MHz or higher. Always buy more bandwidth than you currently need, because your projects will grow.

Pay attention to the frequency range for different waveform types. Many generators advertise a maximum frequency for sine waves but deliver much less for square and arbitrary waveforms. For example, a unit rated for 30MHz sine may only produce clean square waves up to 15MHz. Check the specs for each waveform type you plan to use.

Sample Rate and Resolution

The sample rate, measured in MSa/s (megasamples per second), determines how accurately the generator can reproduce waveforms. Higher sample rates mean smoother signals and better fidelity. A 200MSa/s generator produces noticeably cleaner signals than a 125MSa/s unit at the same frequency. The 14-bit vertical resolution found in most modern DDS generators provides adequate amplitude precision for most applications.

If you work with arbitrary waveforms, also look at the waveform length or memory depth. Longer waveform lengths let you store more complex custom signals. Budget generators typically offer 2048 to 8192 points, while professional units can go into millions of points.

Channel Count

Single-channel generators work fine for basic testing, but dual-channel units are worth the extra cost for most users. Two channels let you generate two independent signals simultaneously, which is essential for testing differential circuits, stereo audio, quadrature signals, and any application requiring phase relationships between signals. Every generator in our top picks list offers dual-channel output.

Waveform Types and Modulation

At minimum, any bench generator should produce sine, square, triangle, and sawtooth waves. Arbitrary waveform capability lets you create custom signal shapes, which is essential for testing specific circuit responses. Look for modulation features like AM, FM, PM, and FSK if you work with communication circuits or need to simulate real-world signal conditions.

Sweep and burst modes are underrated features that you will use more than you expect. Sweep mode automatically varies frequency over a range, which is perfect for frequency response testing. Burst mode outputs a set number of waveform cycles on trigger, useful for testing transient responses.

Build Quality and Interface

A generator that slides around your bench every time you press a button is more than annoying; it can knock cables loose and disrupt your measurements. Weight matters. Units under 3 pounds tend to move around, while heavier units like the Rigol DG1022Z at 7.7 pounds stay planted. If you choose a lightweight model, consider adding rubber feet or using a non-slip mat.

The user interface can make or break your daily experience. Numeric keypads for direct frequency entry save time. Rotary encoders are good for fine adjustments. Touchscreens are convenient but add cost. Consider how you prefer to interact with your equipment and choose accordingly.

Use Case Recommendations

For hobbyists and students, the Koolertron 15MHz or Seesii 15MHz models provide more than enough capability at an accessible price. If you are building your first serious lab bench, the OWON DGE1030 at 30MHz or the Koolertron 60MHz offer great value with room to grow. Audio engineers should look at the Seesii 60MHz for its clean audio-band performance. Professionals who need reliable daily performance should invest in the Rigol DG1022Z.

For field work and process control, the TestHelper TH-71B and Riiai SG003A are specialized tools that fill specific niches better than any bench generator can. And if you just want to learn about signal generation without spending much, the DIY kit or the Seesii FG-200 pocket generator are low-risk starting points.
