Introduction

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.
