[:SOURce[<n>]]:SWEep:TRIGger:SOURce
Syntax
[:SOURce[<n>]]:SWEep:TRIGger:SOURce {INTernal|EXTernal|MANual}
[:SOURce[<n>]]:SWEep:TRIGger:SOURce?
Description
Sets the sweep trigger source of the specified channel to Internal (INTernal), External (EXTernal), or
Manual (MANual).
Queries the trigger source of the sweep of the specified channel.

Remarks
 The generator outputs continuous sweep waveforms when the internal trigger is selected. The trigger
period is determined by the specified sweep time (
[:SOURce[<n>]]:SWEep:TIME), return time
(
[:SOURce[<n>]]:SWEep:RTIMe), start hold ([:SOURce[<n>]]:SWEep:HTIMe:STARt), and stop hold
time (
[:SOURce[<n>]]:SWEep:HTIMe[:STOP]).
 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
(
[:SOURce[<n>]]:SWEep:TRIGger:SLOPe) with a specified polarity, a sweep is initiated.
 In the Manual trigger, the instrument initiates a sweep on the corresponding channel immediately each
time the trigger command (
[:SOURce[<n>]]:SWEep:TRIGger[:IMMediate]) is sent (the trigger
command is only valid when the output of the specified channel is enabled).
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns INT, EXT, or MAN.
Example
:SOUR1:SWE:TRIG:SOUR INT /*Sets the trigger source of the sweep of CH1 to Internal.*/
:SOUR1:SWE:TRIG:SOUR? /*Queries the trigger source of the sweep of CH1 and the query returns
INT.*/
