Descriptions of the Measurement Functions— <function> (Cont.)

:MEASure[:SCALar][:VOLTage]:PHASe? [(@1),(@2)]

Measures Phase.

The measurement arming is coupled to “auto.”

The trigger settings are coupled so that both channels 1 and 2 have auto-trigger enabled at 50% with a positive slope.

<source_list>

 

range:

(@1), (@2)

default:

(@1), (@2)

:MEASure[:SCALar][:VOLTage]:PTPeak? [(@1)(@2)]

Measures Peak-to-Peak Voltage.

<source_list>

range:

(@1) (@2)

default:(@1)

:MEASure[:SCALar][:VOLTage]:PWIDth? [<reference>][,(@1)]

Measures Positive Pulse Width .

The measurement arming is coupled to “auto.”

The <reference> specifies the point on the pulse where the positive 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.
