Title: Current ranger connected to Oscilloscope. Current to voltage conversion.
Post by: ms0260047 on September 24, 2020, 05:44:14 PM
Hi All,

For our project, we want to record voltage and current continuously for our DUT. I was able to twist some code in the current ranger so it stops auto shut off.

My main question now is that how do I convert the value display on the oscilloscope into the actual current value? From what I understand, we have to use ohm's law to do so. We are using the current ranger in the μA mode. What is the internal resistance of the current ranger?

Thank you,
Vincent

The raw output is in 1mV per mA/uA/nA depending on which range it is. If its uA then its 1mV per uA at output.
