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:

 

:TRIG:SOUR INT

Select internal osc. as pulse trigger

 

:PULS:PER 25NS

Set pulse frequency to 25 ns

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:

 

:TRIG:SOUR EXT

Select ext. CLK-IN as pulse trigger

 

:PULS:PER:AUTO ONCE

Measure period at CLK-IN

 

:PULS:PER?

Query pulse period

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.
