Input accuracy for DC or AC coupled signals

User Question

Is the input accuracy (amplitude?) for DC or AC coupled signals?

If for AC coupling, how does the input accuracy vary as a function of the frequency of the input signal?

The input accuracy is defined for the DC coupling. AC coupling is a simple hardware filter. It will attenuate the amplitudes at low frequencies and will change the phase as the standard IIR coupling filter does.
