Note.
If an average-reading voltmeter is used to measure the “DC
voltage” of a waveform, the reading may not agree with the DC Offset
setting of the function generator. This is because the waveform may have
a non-zero average value that would be added to the DC Offset.
You may occasionally see ac levels specified in “decibels relative to
1 milliwatt” (dBm). Since dBm represents a power level, you will need to
know the signal’s RMS voltage and the load resistance in order to make
the calculation.
