SCPI Instrument Command List

Command

:SYST:WARN:STR?

Long

:SYSTem:WARNing:STRing?

Form

Query

*RST value

Not applicable

Description

Use this command to read all the currently active warning messages. The

 

warning messages are concatenated to form a single string with a “;” as

 

separator between the messages.

Command

:SYST:WARN:BUFF?

Long

:SYSTem:WARNing:BUFFer?

Form

Query

*RST value

Not applicable

Description

Use this command to read the maximum possible number of characters

 

that could be returned by :SYST:WARN:STR? if all warnings were active.

Command

:TRIG:COUNt

 

Long

:TRIGger[:SEQuence[1]]:COUNt

Form

Set & Query

 

Parameter

Numeric

 

*RST value

1

 

Specified limits

1 to 65 536

 

Description

Use this command to set/read the number of trigger events (pulse

 

periods) to be generated for each arming event. This corresponds to

 

selecting the event mode on the MODE/TRIGGER SCREEN:

 

PULSES

Set a trigger count to 1 so that a single pulse period is generated for

 

 

each arming event. The instrument is in pulse (stream) mode.

 

BURST of

Set a trigger count of 2 to 65536 so that a burst of 2 to 65536 pulse

 

 

periods is generated for each arming event.
