Notes
1. The reference (threshold) can be specified as a percentage of the
peak-to-peak amplitude or as an absolute level in either the
CONFigure
or
MEASure?
command.
2. Absolute references are relative to the amplitude of the signal and must take
into consideration the counter’s input coupling and impedance settings.
3. See Chapter 4 for information on configuring the input signal path which
includes coupling and impedance.
