DC offset measurement

[jack249]

I wish to write a program to measure DC offset value from a AC waveform by using NI PXI 4065.

The programming language i'm using is Visual C++.

I would like to know that is that any particular function or parameter is used for measuring DC offset?

Or i just use niDMM_Read() to read the measurement and use niDMM_FormatMeas() to measure and get the DC offset value?

Hello, Jack249!

No, there is not a specific function dedicated to measuring offset - your method of measuring the signal and comparing is correct.

According to the specifications for that DMM, if you are using analog functions AC coupling will automatically be enabled. This, of course, should elimiate your DC offset anyway.

Best,
