Remote Interface Command
Use the following commands for making pulse width measurement:
[:SENSe]:FUNCtion[:ON] “[:][XNONe:]PWIDth [1]”
[:SENSe]:FUNCtion[:ON] “[:][XNONe:]NWIDth [1]”
Or
:CONFigure[:SCALar][:VOLTage]:PWIDth [(@1)]
:CONFigure[:SCALar][:VOLTage]:NWIDth [(@1)]
:READ[[:SCALar][:VOLTage]:PWIDth]?
:READ[[:SCALar][:VOLTage]:NWIDth]?
Or
:MEASure[:SCALar][:VOLTage]:PWIDth? [(@1)]
:MEASure[:SCALar][:VOLTage]:NWIDth? [(@1)]
3.7 Duty Cycle Measurement
The Duty cycle is defined by the following formula, and with its results
from 0 to 1:
Duty Cycle = (Positive Pulse Width)/Period
The dutycycle mode is only available to apply on Channel 1. Moreover,
auto triggering is enabled by default for duty cycle measurement, and
the trigger levels are set to the 50% points of each signal. One may
manually disable the auto triggering and change the trigger levels and
