SCPI Instrument Command List

Command

:ARM:EWID

 

Long

:ARM[:SEQuence[1]STARt][:LAYer]:EWIDth[:STATe]

Form

Set & Query

 

Parameter

ON OFF 1 0

 

*RST value

OFF

 

Description

Use this command to enable the EXT WIDTH trigger mode available on

 

the MODE/TRIGGER SCREEN. When EXT WIDTH mode is switched on, the rest of

 

the :ARM and :TRIG system is disabled.

 

In EXT WIDTH mode a signal applied to the EXT INPUT determines the

 

width and period of the output signal(s) from the instrument. You can

 

still control the edge transition times and levels of the output signal(s).

Command

:ARM:FREQ

 

Long

:ARM[:SEQuence[1]STARt][:LAYer]:FREQuency[:CW][:FIXed]

Form

Set & Query

 

Parameter

Numeric

 

Parameter Suffix

HZ with engineering prefixes, e.g.: MHZ is Megahertz.

*RST value

100 kHz

 

Specified Limits

1 mHz to 50 MHz

 

Description

Use this command to program the frequency of the PLL (INTernal2)

 

when it is used as the :ARM:SOURce for internal triggering of pulses,

 

bursts or patterns.

 

 

If you are using the PLL as :TRIGger:SOURce to set the pulse frequency,

 

use the [:SOURce]:FREQuency[:CW:FIXed] command.

Example

To set up bursts of four 20 MHz pulses occurring at a burst rate of 2 MHz:

 

:TRIG:SOUR INT

Select internal osc. as pulse period source

 

:FREQ 20 MHZ

Set pulse frequency to 20 MHz

 

:ARM:SOUR INT2

Select PLL as triggering source

 

:ARM:SENS EDGE

Sense edge of PLL signal

 

:ARM:FREQ 2 MHZ

Set triggering frequency to 2 MHz

 

:TRIG:COUNT 4

Set burst length to 4
