Hello.
I use my S.G. (signal generator) in order to calibrate a chip I own which performs measurements.
I connect the S.G.'s pins to my chip and I need to know exactly what voltage is inserted into the chip by the S.G.
I measured the S.G.'s pins with fluke (multimeter), and the fluke showed unstable results.
I disconnected the S.G. pins from the chip, and the fluke still showed unstable resutls.
For example, when I set the S.G. to output 100mVp, the fluke's results were moving between 70.1mVrms and 73.2 mVrms - it stays a few moments on 73.2mVrms, then went down for a few moments to 70.1mVrms, and so on.
Did someone experience it and could tell me what is the problem?
It means that the S.G. is not ok?
Thank you.
