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.

Would it be possible to make a modification and add an interior lithium battery to make it portable? Thank you.

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. 1) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sttpgZkDx48.html 2) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XWJOChu1ZMc.html

It is inexpensive but wow, way off on max freq spec. What does the filter actually do, clean up the waveforms at all?

@mightypez Год назад

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.
