Review: Really full feature set including flexible modulation modes. Great price for this flexible generator - Impressive functionality for this price range. Besides the many normal signal generator signal types and adjustment here are some experiences of note. - If you save to memory 00 that acts as the power-on default (1 review here said this could not remember a power on default but that is inacurate, just set memory 00 and that is the power on and in my case is now 1khz sine and my default turns that darn buzzer OFF! - LOVE the modulation modes and ability to have external modulation input. I ran the 60mhz unit up into ham band 28mhz and put am modulation on the signal from the 'MOD' input AND from internal or from channel 2 feeding the MOD input. - The user interface is not all that bad but when you do have to read the manual (RTFM) the wording can be awkward likely from translation but at least the manual is very complete. Really like all the features and display of what is going on. Really great features for a very fair price.
Review: Loads of Fun! - I'm having a blast just getting to know all the things this signal generator can do! It does all the obvious things -- sine, square, pulse waveforms, etc., and it also is capable of a whole lot more waveforms -- rising/falling sawtooth, triangle, and a bunch of waveforms I'll have fun figuring out what they might be useful for. You can easily adjust the phase between the two outputs, and it has every sort of modulation you can imagine. One useful feature I've discovered is the burst mode, where for example you can output a burst of say 10 cycles of say a 1kHz tone (takes 10ms). I've used this to examine the output of a high power amplifier where I don't want to overstress it. As others have pointed out you can easily adjust the duty cycle of the output, but not with sine or square waves for which only symmetrical output is available. I'm not clear who actually manufactures this device -- it looks like it is available with various labels, but is actually a JDS 8000 manufactured by Hangzhou Junce Instruments. The short manual it comes with is pretty useful but I got a more complete manual online from Hangzhou Junce. I have a couple of complaints. 1 - when you switch it on it doesn't go back to the settings you last used it at, which would be very useful. Instead it reverts to the default setting of 10kHz sine wave at 10v p-p, which would not be good to input into a conventional audio amplifier or preamp, which is what I'm using it for mainly. It has multiple memories where you can store settings, but you have to remember to do that manually each time you turn it on. 2 - the output level is indicated only in peak-to-peak volts, which is useful for many waveforms but not so much for sine waves -- I wish you could switch to other units such as rms volts. 3 -- minor complaint -- the connecting lines for the device use standard BNC connectors to attach to the actual device, but have some pretty crude alligator clips on the other end -- the kind where when you squeeze on the vinyl insulation surrounding the alligator clip it tends to just rotate around rather than open. Not a big deal if you already have some good BNC cables with quality microclips or something similar. 4 -- THD is pretty high -- around 0.3% or so, meaning although this waveform generator is going to be very useful for many things, measuring amplifier THD is not going to be one of them. On the other hand I don't think there are many general purpose waveform generators with very low THD -- you need another source for such a signal.

## 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

### ⭐⭐⭐⭐ Incredible value.
*by B***N on December 11, 2024*

I’m impressed by the capabilities of this signal generator. Not long ago, a device like this would have been prohibitively expensive. The unit is compact and lightweight yet performs exceptionally well, making it a great addition to any test bench. While I’m very satisfied with its functionality, there are a few design elements that could be refined. The display and menus, although in English, retain some stylistic influences from the original Chinese design. This has no impact on usability but may feel slightly unconventional to some users. Setting the operating frequency is straightforward, though the process is a bit unconventional—you select a specific decimal position and adjust the value with the control knob. One minor inconvenience is that while the unit offers plenty of memory slots for saving operational states, it always starts up with its default settings rather than remembering the last frequency and mode used. It would be much more user-friendly if it resumed the previous operational state upon powering on. That said, these quirks are minor and don’t detract from the unit’s overall performance. While it’s not reference-grade test equipment—understandable at this price point—it is an extremely capable and excellent value for general-purpose use.
