For desktop, definitely don't get a MicSig. It's less capable (no active probe I/F, which is very important in my daily works)
I don't know what is I/F, but I don't see what micsig is really missing from "desktop" oscilloscopes in the
same price range. A good active probe costs more than this small device. Don't compare it with MSOX3054A
.
I use it as a desktop oscilloscope and I'm quite happy about it. It's not ideal, the screen is glossy, the stand is not adjustable, the fan is a bit more loud than it should, UI is a bit slow (still faster than R&S!), but it does the job.
