Agilent 81131A: 1.25 ns to 999.9 µs
Agilent 81132A: 0.75 ns to 999.9 µs
Description
Use this command to program the width of the pulse signal. If you want
to set width as dutycycle use
[:SOURce]:PULSe:DCYCle[1|2]
.
If you want the pulse-width to remain constant when the pulse period is
varied (rather than the dutycycle) use
[:SOURce]:PULSe:HOLD[1|2]
WIDTh.
Example
:PULS:WIDT1 50NS
Set OUTPUT 1 pulse width to 50 ns
:PULS:HOLD1 WIDTH
Hold pulse-width constant with varying period
