ACQUISITION - TRIG_SLOPE, TRSL 

The TRIG_SLOPE command sets the trigger slope of the specified trigger source.  The TRIG_SLOPE? 

query returns the trigger slope of the selected source. 

Command Syntax 

<trig_source>:TRig_SLope <trig_slope> 

<trig_source>:= {C1,C2,C3,C4,LINE,EX,EX5} 

<trig_slope>:= {NEG, POS} 

Query Syntax 

<trig_source>:TRig_SLope? 

Response Format 

<trig_source>:TRig_SLope <trig_slope> 

Example 

The following instruction sets the trigger slope of Channel 2 to negative: 

C2:TRSL NEG 

Related Commands
