Would it be possible to make a modification and add an interior lithium battery to make it portable? Thank you.
Thanks for this useful video. I have few questions:
1) What is the maximum current it can provide?
2) Does it come with a power adapter? If no, which one to use?
3) Can I run it from my computer too? I mean is it possible to interface it with a free software and operate it accordingly?
4) Can we generate frequency in decimals too, like 114.223Hz?
Hello and thank you for your reply
1) Next time I am using the device, I will measure
2) No adapter, it uses a standard provided usb cable, I power it from my nearby laptop, but have also used a phone charger.
3) there is no interface other than the front panel buttons.
@@mightypez Thanks for your reply
I got one of these too. It had most of the mechanical issues yours had and suffered from counterfeit op-amps. I was eventually able to resolve all the issues. They can be made to meet specifications. Here are two videos where I go through the steps.

It is inexpensive but wow, way off on max freq spec. What does the filter actually do, clean up the waveforms at all?
I noticed a "slight" reduction in noise (or sometime just shifting the noise) at the higher freq like 10K. it did nothing that would change / correct the underlying waveform, so when they started to break down (square wave looking like Triangle) no benefit. Honestly, after trying it a few times, I never use it.
Yes, for me way off, but thankfully I just wanted a cheap low freq sin wave to drive a breadboard circuit clock for low freq testing, so it works for me.
I can't hear it ??😢
Sorry to “hear” that. I can assure you I am speaking in the video, and I replayed it just now to verify. Maybe window focus if viewing on phone app?
It not the video... is the generator I got lol
