AC coupling effect of ADC

(1/1)

fmcuser:
I am using an ADC of FMC150 on ML605. The ADCs on FMC150 are AC coupled. There are capacitors in front of these ADCs. I input multiple waveform e.g. 100-kHz square pulses to one of the ADCs. The waveform that were sampled by the ADC was distorted. I think this is due to the frequency characteristics of the capacitors in front of the ADC.
Can anybody give me any advice to remove this AC coupling effect?

Dear Sir,


Not as I am aware of. The most obvious solution is to use a DC coupled card, the FMC151 is the DC coupled version of the FMC150.
