Actually I have a Hantek DSO4102C, that I bought specifically for that, particularly because it advertised a "Bode plot" functionality which turned out to be inexistent! No sweeps, no Bode display. 8-bit resolution makes the curves quite hairy, to the point I deemed it unusable and put it to retirement.It may be a bit of a topic but I wonder if anyone has considered using an oscilloscope with a waveform generator (or has any experience already) to measure the frequency range up to 100kHz or more?
Actually, it seems very much oriented to MEMS/ECM mics. Line input looks like a collateral.inputs are fully configuarble either for analog or digital mic or bal/unbal line , even input impedence can be set through software 2.5 ,5k ,10k,20k , 50 db of programable gain
Actually, the EU ex-VAT price is 224€ ($266).$199 dollars is great value for what you get here
I couldn't find any datasheet for the chip. All links point to the EVM.Specs of frequency responce at higher sample rates shows a progressive degradation in out of band performance relative to the lower rates , factors of around .45(48khz) vs .1(768khz) Fs for +/-0.05db . Should be easy to program an eq button to counteract the fall off upto several hundred khz for frequency response measurements.
Thanks. The worst thing is always that you can't usually try the real thing before you buy it. This Keysight looks very good to me, it’s not too expensive, but I haven’t tried it so I’m not 100% sure. My "problem" is that I don't know at the moment any other software/hardware that is affordable for me that could measure the frequency range up to somewhere around 200kHz and give some *.csv or such file as a result.Actually I have a Hantek DSO4102C, that I bought specifically for that, particularly because it advertised a "Bode plot" functionality which turned out to be inexistent!

The filters are so steep there would probably be enormous noise build-up to achieve a minor improvement (less than 1/3 octave).I was wondering if the EQ section on board the card could be used to taylor response at high frequencies. Ok it probably will bring up extra noise and distortion but were not so worried about that when doing bandwidth measurements .
