You cannot set the pulse period if you have selected the CLK-IN
connector as the frequency source (:TRIG:SOUR EXT).
To set the pulse period using the internal oscillator:
:TRIG:SOUR INT
:PULS:PER 25NS
:PULS:PER:AUTO
[:SOURce]:PULSe:PERiod:AUTO
Event
ONCE
Not applicable
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?
To measure the period at the CLK-IN connector:
:TRIG:SOUR EXT
:PULS:PER:AUTO ONCE
:PULS:PER?
:PULS:TDEL[1]
[:SOURce]:PULSe:TDELay[1]

10 ns to 999.5 s (max. period –10 ns)
Use this command to program the delay of the trailing edge of the pulse
relative to the start of the pulse period. This is an alternative method of
programming the pulse width.
Select internal osc. as pulse trigger
Set pulse frequency to 25 ns
Select ext. CLK-IN as pulse trigger
