Description

Use this command to program the width of the pulse signal. If you want

 

to set width as dutycycle use [:SOURce]:PULSe:DCYCle[12].

 

If you want the pulse-width to remain constant when the pulse period is

 

varied (rather than the dutycycle) use [:SOURce]:PULSe:HOLD[12]

 

WIDTh.

 

Example

:PULS:WIDT1 50NS

Set OUTPUT 1 pulse width to 50 ns

 

:PULS:HOLD1 WIDTH

Hold pulse-width constant with varying period
