Doing two different scales should avoid that. I can use a standard low
value current sense resistors and DiffAmp or InAmp for the currents in
the mA range,
I did just thing that I should add, that the current pulses from the transmitter
are narrow in time, a few tens of microseconds. The capacitors on the
actual board under test take care of most of that, from being seen by
