[:SOURce[<n>]]:SWEep:TRIGger[:IMMediate]
Syntax
[:SOURce[<n>]]:SWEep:TRIGger[:IMMediate]
Description
Triggers a sweep immediately on the specified channel.

Default
[<n>]
Discrete

1
Remarks
 This command is only applicable to manual trigger (
[:SOURce[<n>]]:SWEep:TRIGger:SOURce) and is
only valid when the output of the corresponding channel (
:OUTPut[<n>][:STATe]) is enabled.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Example
:SOUR1:SWE:TRIG /*Triggers a sweep immediately on CH1.*/
[:SOURce[<n>]]:SWEep:TRIGger:SLOPe
Syntax
[:SOURce[<n>]]:SWEep:TRIGger:SLOPe {POSitive|NEGative}
[:SOURce[<n>]]:SWEep:TRIGger: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
 Sets the edge type of the trigger input signal, i.g. selects to trigger on the rising edge or falling edge of
the trigger input signal.
 This command is only applicable to the external trigger (
[:SOURce[<n>]]:SWEep:TRIGger:SOURce).
In the External trigger, the signal generator receives the trigger signal input from the rear-panel
[Sync/Ext Mod/Trig/FSK] connector of the specified channel. Once it receives a TTL pulse with a
specified polarity, a sweep is initiated.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns POS or NEG.
Example
:SOUR1:SWE:TRIG:SLOP POS /*Sets the edge type of the trigger input signal of CH1 to Rising edge.*/
:SOUR1:SWE:TRIG:SLOP? /*Queries the edge type of the trigger input signal of CH1 and the query
returns POS.*/
