Hi,
I am looking for some instrument/sensor to do a contact less current sensing with 100kHZ frequency.
This is a switching current waveform with an inductor was switched at 100kHZ. My typical current waveform is 50mA (DC) with a 0-20mA 100khZ AC imposed on it. I need to detect this AC component.
My trouble is, I can not probe anything on board and only way to find this current is do have some contactless sensing on current carrying wire.

I need it something for a lab measurement so price is not an issue.
Please suggest if someone have any info.

Thanks in Advance;

Umesh
