It's stable, has a clean output, tons of features and it's really easy to use. The screen is well lit, and it only takes a short time to learn the UI. I work on audio gear, and it's got everything that I need. The stability is good enough for my wow/flutter test, and the multifrequency waveform is perfect to troubleshoot filters. Everything works like it should. The only negative would be the thing is so light, you have to have a hand on top when you push a button or you'll push it off the shelf. Tie it down some way, or just learn to hold it while you use the buttons. I'm very happy with mine. Review: Excellent value - I bought this to generate audio-frequency signals for testing amplifiers, signal adapters, etc. It took a little trial-and-error to figure out some of the controls, but in the end the unit worked flawlessly for my needs and is easy to operate. The documentation is not very extensive, but if you know something about test equipment you'll figure it out. The unit is fairly compact and lightweight (almost too light – weighs practically nothing). The construction is not super-rugged, but for everyday use in a home or office it's fine. I can't speak to the more advanced capabilities (e.g., the PC interface) because I haven't used them yet, but the basics are great. I wish all my equipment worked this well. ## Features - Arbitrary Waveform Generator adopts large scale FPGA integrated circuit and high-speed MCU microprocessor. The internal circuit adopts the active crystal oscillator as the benchmark. So the signal stability is greatly strengthened. - Using Dual-channel DDS signal and TTL electric level output to generate precise, stable, low distortion output signal. includes Sine wave, Square wave, Triangle wave, Saw toothwave, Pulse wave, white noise, user-defined waveform etc. each channel can be independently set the parameters. - With linear sweep(Max. up to 999.9s) and logarithmic frequency sweep functions.Has a frequency measurement, period measurement, positive and negative pulse width measurement and counting function. - Storage feature: You can store 99 groups instrument state parameters set by the user, can be called up to Reproduce.The frequency output of Sine wave can be up to 15MHz. 200MSa/s sampling rate. It has 60 positions for saving user-defined waveform. Waveform Length of each one is 2048 and vertical resolution is 14 bits - This Signal Generator is the ideal instrument for electronic engineering, laboratories, production lines, teaching and scientific research. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 473 Reviews | ## Images ![Upgraded 15MHz DDS Signal Generator Counter,High Precision Dual-Channel Arbitrary Waveform Function Generator Frequency Meter 200MSa/s (15MHz) - Image 1](https://m.media-amazon.com/images/I/61H2CCyJchL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How many volts does the generator put out?** A: The settings allow you to enter up to 20volts. Open circuit, I read a max of 21 volts peak to peak. When connected to a 50 ohm load, the voltage measured drops in half (I assume that the impedance of the Koolertron is 50 ohms, so attaching a 50 ohm load would cut the voltage in half). The difference between the setting and what I measured on my scope could be calibration of either device. I am reading some noise on the signal, so that could also be causing the slight difference. Hope that helps. **Q: Can it generate a 20 Hz sine wave and add 50-60 Hz to it?** A: Yes,It can generate a 20 Hz sine wave. But what do you meanning of "add 50-60 Hz to it"? If you have any problem can feel free to contact our customer service email"karstonecorp@gmail.com ",we are glad to service our customer. **Q: What does “Full range of 0.01μHz frequency resolution” mean exactly 2digits** A: It is means 0.00000001Hz. **Q: What's the maximum current it can put out?** A: the maximum output current is 0.1A ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great functionality for the price *by W***E on May 26, 2020* This is a great audio generator for the money.

First the bad: The BNC jacks or cables are defective but mostly usable. Just breathing on where the cables connect to the machine creates horrible noise visible on an oscilloscope even when the channel is turned off. Some weights on the cables to keep them still is a kludgy fix. The cable is also very stiff compared to oscilloscope cables. Finding the sweet spot where the signal is clear and uninterrupted reminds me of the old days of doing reception ballet with old TV sets. I'm not yet 100% certain, but the voltage might randomly jump up and down slightly ( a few mV @ 1V) when going from one frequency to another. The 2nd channel has the same noise problem. The display for it is small and hard to see. But may be a good tradeoff so that the 1st channel is easier to see on the smallish screen. The good: The user interface is very intuitive. I didn't need the manual to figure out how to change frequency, amplitude, waveform, or do sweeps. It is actually the best I've seen on electronics test equipment. It boots up quickly. Just eyeballing it, but it seems reasonably accurate. They went to great pains to keep the price down. Other: It is very lightweight because the plastic case is mostly full of air. It is powered by low voltage from a wallwart(ugh), but that means it could easily be made battery powered and portable. There is plenty of room in the case to add a battery pack. Its brain appears to be made by Lattice Semiconductor, I can't see exactly which chip but I assume it is an FPGA. There is a place for a 6(?) pin header on the mainboard, and a 5(?) pin header on the front panel interior which may be handy for hacking it. There are also 4 very small, cellphone antenna like sockets on the mainboard, likely for testing, but which could possibly find other uses. Except for screwing up the cables (or sockets) manufacturing, I'd say this is a good value for price. It is probably good enough for hobbyists getting their electronics feet wet, high school students, and curious characters. Obviously it isn't intended for advanced hobbyists, scientists or electronics engineers, or those who just like the feel of high quality. Although I fall into one of the former categories, I wish I had spent 3x more for a something like a Rigol. I think I would feel differently if they had just gone the extra meter and spent a few more cents on the connectors and added rubber feet for grip so that I wouldn't feel like the magic smoke will puff out of it soon and to help me trust it a bit more as far as accuracy and that that horrendous noise won't damage delicate components. ## Frequently Bought Together - Koolertron Upgraded 15MHz DDS Signal Generator Counter,High Precision Dual-Channel Arbitrary Waveform Function Generator Frequency Meter 200MSa/s (15MHz) - onelinkmore BNC Male Plug to 2X 4mm Dual Banana Female Jack Socket Binding Post RF Coax Coaxial Splitter Connector BNC Banana Adapter for HF Radio Antennas Oscilloscope DVM Pack of 5 - Universal Oscilloscope Probe with Accessories Kit 100MHz Oscilloscope Clip Probes with BNC to Minigrabber Test Lead Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/45055267-upgraded-15mhz-dds-signal-generator-counter-high-precision-dual-channel](https://www.desertcart.tn/products/45055267-upgraded-15mhz-dds-signal-generator-counter-high-precision-dual-channel) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-15*
