SCPI Instrument Command List
You cannot set the pulse period if you have selected the CLK-IN
connector as the frequency source (
:TRIG:SOUR EXT
).
Example To set the pulse period using the internal oscillator:
Command :PULS:PER:AUTO
Long
[:SOURce]:PULSe:PERiod:AUTO
Form Event
Parameter
ONCE
*RST value Not applicable
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 To measure the period at the CLK-IN connector:
Command :PULS:TDEL[1]
Long
[:SOURce]:PULSe:TDELay[1]
Form Set & Query
Parameter Numeric
Parameter Suffix
S
with engineering prefixes.
*RST value 100 ns
Specified Limits 10 ns to 999.5 s (max. period –10 ns)
Description 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.
:TRIG:SOUR INT
:PULS:PER 25NS
Select internal osc. as pulse trigger
Set pulse frequency to 25 ns
:TRIG:SOUR EXT
:PULS:PER:AUTO ONCE
:PULS:PER?
Select ext. CLK-IN as pulse trigger
Measure period at CLK-IN
Query pulse period
