Hi Barry,
Appreciate the response. By sensitive, I meant that since currents can go as low as a few hundred uA's, the current probe doesn't produce accurate readings at this level. I have tried this out with , say a resistor and a few capacitors to understand if low level current are measurable and there is some error. The probe has 5mV / mA gain. Perhaps this can be gained up with a low noise amplifier to reduce noise at low current levels?
I have tried that method out with current and voltage waveforms, however, there is an inherent propagation delay to each current and voltage probe that messes up the measurement (eg: MATH on CH1 and CH2)
Best,
Nikhil
