AFE (analog front end)

We'd like to test simultaneous sampling of voltage and current needed for accurate power and efficiency analysis. That will require at least 6 channels for Vin, I(in,low), I(in,high) and Vout, I(out,low), I(out,high) since current will be acquired on two ranges: e.g. 20 mA / 2 A or 50 mA / 5 A. Sampling rate has to be at least 200 kHz. The same is with input bandwidth.
