Description
Use this command to set/read the pulse period. Select the pulse period
source using
:TRIGger:SOURce
. The currently selected source is
programmed by this command. Note that the specified limits and
available resolution depend on the selected source.
You cannot set the pulse period if you have selected the CLK IN
connector as the frequency source (
:TRIG:SOUR EXT2
).
Example
:TRIG:SOUR INT
Select internal PLL as pulse trigger
:PULS:PER 25NS
Set pulse frequency to 25 ns

Description
Use this command to measure the period at the CLK IN connector. If the
CLK IN connector is the selected pulse period source, you can then read
the measured value with
:PULS:PER?
Example
:TRIG:SOUR EXT2
Select ext CLK IN as pulse trigger
:PULS:PER:AUTO ONCE
