Also as you can see below the values I get depend strongly on the reference resistor I use for example
10k DUT
10 Ohm reference, Amplitude = 1V
100 Ohm reference, Amplitude = 1 V
1 kOhm reference, Amplitude = 1 V
10kOhm reference, Amplitude = 1V
100 kOhm reference, Amplitude = 1V
1 MOhm reference, Amplitude = 1V
As you can see the results are inconsistent and only the 100 Ohm and 1 MOhm resistors give correct measurements
Do you think this is a power-related issue? Do I need a powered USB hub or an additional 5V power supply or something?
I am trying to find out what's going on so that we can use it correctly in the lab.
