Description Use this command to set/read the delay between the leading edges of the two pulses in double-pulse mode. The first pulse always starts at the start of the pulse period.

If you want the double delay to remain constant when the pulse period is varied (rather than the double delay as percentage of period) use

[:SOURce]:PULSe:DOUBle[1]:DELay:HOLD TIME.

Example

To set and hold the double-pulse delay:

 

 

:PULS:DOUB ON

Switch on Double pulses on OUTPUT

 

:PULS:DOUB:DEL 500NS

Set interpulse delay to 500 ns

 

:PULS:DOUB:DEL:HOLD TIME

Hold interpulse delay fixed with varying
