Could you not add some voltage input to the negative feedback with a POT and trim out the DC offset in a higher BW opamp or does the DC offset change?
It would be very helpful for me to have something that is close but does not need to be perfect. If I could be within 1 mA on a 10mA scale that would be great but I would really like to be able to see transients on an oscilloscope. I have an HP current clamp which can do I think 1 mA per division but it is sooo huge and the clamp always gets in the way. I know on my HP current clamp I have to trim it to be DC accurate before I apply power. Can we not do the same with this?
Not sure if I am being WAY over simplistic with this.
