Background: I've been using the AD2/Waveforms to measure/analyze low-level/low frequency signals that have a DC component that we care about.   The signal is in the feedback loop of a system, and the AC & DC components are in ~ 1mV range. We have a 200 Hz LPF with a gain of 10 (offset trimmed) before we feed into the AD2 (and a Keysight Benchtop DMM & a Tek TDS3034C). The attached .png shows the standard "Measurements" of the 1V DC as a reference.   My question is rel
