MHS-5200A function generator teardown / review / reverse engineering
Glapsvin:
I just bought new one for 50$, as previously reported it does seem to be improved from the original terdown. I know the limitations of my new toy and so far I'm very happy with the purchase (performance / price point).

thx, I found it in the meantime on MHInstek website.
Installed and running fine so long.
I wonder about the efforts with excel sheets and export stuff from alternative Software, I have nothing to complain at the moment.
GB did a refund about 25$ plus 125 extra points(2$50).. so no bad deal. :-DD ;D

For those interested, I finally got a hold of one of the new MHS5200A units and did a short overview of the new features, plus a teardown, circuit analysis, and performance review.
TL;DW: The analog front-end underwent a not-insignificant redesign. The newer models generate much nicer square waves, at the expense of increased high frequency noise. Slew rate distortion is still an issue. Generally poor performance when compared to a "proper" signal generator, but for the price it's still a good bang-for-the-buck, especially if you're only interested in lower frequency signal generation and don't mind the HF noise in the output signal.

I watched that video last night. Prolly good enough for my needs.
I missed the part whether this can do a sweep or adjust frequency via dial on the fly, or if needed to be paused/stopped to adjust.

Thanks for the video. I'll try the 100pf cap....
