:TRIGger[<n>][:IMMediate]
Syntax
:TRIGger[<n>] [:IMMediate]
Description
Generates a trigger on the specified channel.
Parameter
Name
Type
Range
Default
[<n>]
Discrete
1|2
1
Remarks
 This command is only applicable to the burst output (
[:SOURce[<n>]]:BURSt[:STATe]) or sweep
output (
[:SOURce[<n>]]:SWEep:STATe) in manual trigger (:TRIGger[<n>]:SOURce).
 When [<n>] is omitted, the system generates a trigger on CH1 by default.
 If the output of the corresponding channel is not enabled, the trigger will be ignored.
Example
:TRIG1 /*Generates a trigger on CH1.*/
:TRIGger[<n>]:SLOPe
Syntax
:TRIGger[<n>]:SLOPe {POSitive|NEGative}
:TRIGger[<n>]:SLOPe?
Description
Sets the edge type of the trigger input signal of the specified channel to Rising (POSitive) or Falling
(NEGative).
Queries the edge type of the trigger input signal of the specified channel.

{POSitive|NEGative}
Discrete
POSitive|NEGative
POSitive
Remarks
 This command is only applicable to the burst mode (
[:SOURce[<n>]]:BURSt[:STATe]) (N cycle,
Infinite, or Gated) or sweep output (
[:SOURce[<n>]]:SWEep:STATe) in external trigger
(
:TRIGger[<n>]:SOURce). In the External trigger, the signal generator receives the trigger signal input
from the rear-panel [Sync/Ext Mod/Trig/FSK] connector. Once it receives a TTL pulse with a
specified polarity, a burst output (N cycle, Infinite, or Gated) or sweep output is initiated.
 When [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns POS or NEG.
Example
:TRIG1:SLOP NEG /*Sets the edge type of the trigger input signal of CH1 to Falling edge.*/
:TRIG1:SLOP? /*Queries the edge type of the trigger input signal of CH1 and the query returns
NEG.*/
