SCPI Instrument Command List

Command

:PULS:WIDT[1]

 

Long

[:SOURce]:PULSe:WIDTh[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 width of the pulse signal. If you want

 

to set width as duty cycle use [:SOURce]:PULSe:DCYCle[1].

 

If you want the pulse width to remain constant when the pulse period is

 

varied (rather than the duty cycle) use

 

[:SOURce]:PULSe:HOLD[1] WIDTh.

Example

To set and hold the pulse width:

 

 

:PULS:WIDT 50NS

Set OUTPUT pulse width to 50 ns

 

:PULS:HOLD WIDTH

Hold pulse width constant with varying period

Command

:ROSC:SOUR

 

Long

[:SOURce]:ROSCillator:SOURce

Form

Set & Query

 

Parameter

INTernal EXTernal

 

*RST value

INT

 

Description

Use this command to set/read the reference source for the PLL. If you

 

select the external reference (CLK-IN connector), you can choose to use

 

a 5 MHz or 10 MHz reference signal using :ROSC:EXT:FREQ.

 

INTernal

Lock the PLL to its internal reference

 

EXTernal

Lock the PLL to a reference signal at the

 

 

CLK-IN connector. The external refer-

 

 

ence signal can be 5 or 10 MHz.
