SCPI Instrument Command List

Command

:ARM:SENS

Long

:ARM[:SEQuence[1]STARt][:LAYer]:SENSe

Form

Set & Query

Parameter

EDGE LEVel

*RST value

EDGE

Description

Use this command to select Triggered or Gated mode by choosing

 

whether the instrument arms on the edge(s) or level of the arming signal.

 

When sensing edges, the instrument triggers when the arming signal

 

crosses the selected threshold level (:ARM:LEV) in the selected direction

 

(:ARM:SLOP). This corresponds to the Triggered mode selected on the

 

Mode/Trigger screen when using the front panel.

 

When sensing levels, the instrument triggers as long as the arming signal

 

is above (:ARM:SLOP POS), or below (:ARM:SLOP NEG) the selected

 

threshold level (:ARM:LEV). This corresponds to the Gated mode

 

selected on the MODE/TRIGGER SCREEN when using the front panel.

Command

:ARM:SLOP

Long

:ARM[:SEQuence[1]STAR7t][:LAYer]:SLOPe

Form

Set & Query

Parameter

POSitive NEGative EITHer

*RST value

POS

Description

Use this command to select the trigger slope for the arming signal when

 

triggering on edges. Use EITHer to trigger on both the positive and

 

negative edges of the arming signal. This allows you to trigger at twice

 

the frequency of the arming signal.

 

If you are arming on levels, use this command to select whether the

 

instrument triggers during the positive or negative cycle of the arming

 

signal.
