Specified limits

0.001% to 99.9%, depends on width, transition & period.

Description

Use this command to program the duty cycle of the pulse signal. If you

 

want to set an absolute pulse width use [:SOURce]:PULSe:WIDTh[1].

 

If you want the pulse duty cycle to remain constant when the pulse

 

period is varied (rather than the absolute pulse width use)

 

:SOURce]:PULSe:HOLD[1] DCYCle

Example

To set and hold the duty cycle:

 

 

:PULS:DCYC 25PCT

 

 

Set OUTPUT duty cycle to 25%

 

:PULS:HOLD DCYC

 

 

Hold duty cycle constant with varying period
