Descriptions of the Measurement Functions—<function> (Cont.)
:MEASure[:SCALar][:VOLTage]:NWIDth? [<reference>][,(@1)]
Measures Negative Pulse Width.
The measurement arming is coupled to “auto.”
The <reference> specifies the point on the pulse where the negative pulse width is
determined. This point can be specified as either a percentage or an absolute
voltage. The default units are percent.
The <reference> parameter is used to configure the trigger settings. When the
<reference> is specified as a percentage (or defaulted),
auto-trigger is enabled and auto-trigger levels are set to the specified (or defaulted)
reference value. When the <reference> is specified in volts, auto-trigger is disabled
and the absolute trigger levels are set to the specified reference value.
