// using CONFigure - measure negative width at -500 mV
// reference
*RST // reset to start from known state
CONF:NWID -500 MV, (@1)
INP:COUP DC // set DC coupling
INP:IMP 50 // set input impedance to 50 ohm
READ?
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.
