[:SOURce[<n>]]:SWEep:TRIGger:SOURce
Syntax [:SOURce[<n>]]:SWEep:TRIGger:SOURce {INTernal|EXTernal|MANual}
[:SOURce[<n>]]:SWEep:TRIGger:SOURce?
Description Set the trigger source of the sweep of the specified channel to internal source
(INTernal), external source (EXTernal) or manual source (MANual).
Query the trigger source of the sweep of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
{INTernal|EXTernal|MANual} Discrete INTernal|EXTernal|MANual INTernal
Explanation  In internal trigger, the signal generator outputs continuous sweep waveform.
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
( [:SOURce[<n>]]:SWEep:HTIMe[:STOP] ). You can also set the
[Mod/Trig/FSK/Sync] connector of the corresponding channel at the rear
panel to output trigger signal with the specified edge
( [:SOURce[<n>]]:SWEep:TRIGger:TRIGOut ).
 In external trigger, the signal generator receives the trigger signal inputted from
the [Mod/Trig/FSK/Sync] connector of the corresponding channel at the rear
panel and initiates a sweep each time a TTL pulse with the specified polarity
( [:SOURce[<n>]]:SWEep:TRIGger:SLOPe ) is received.
 In manual trigger, the instrument initiates a sweep in the corresponding channel
immediately each time the trigger command
( [:SOURce[<n>]]:SWEep:TRIGger[:IMMediate] ) is send (the trigger command
is only valid when the output of the specified channel is turned on).
 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 /*Set the trigger source of the sweep of CH1 to
internal*/
:SOUR1:SWE:TRIG:SOUR? /*Query the trigger source of the sweep of CH1
and the query returns INT*/
