:TRIGger[<n>]:SOURce
Syntax :TRIGger[<n>]:SOURce {INTernal|EXTernal|BUS}
:TRIGger[<n>]:SOURce?
Description Set the trigger source of the specified channel to internal (INTernal), external
(EXTernal) or manual (MANual).
Query the trigger source of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
{INTernal|EXTernal|BUS} Discrete INTernal|EXTernal|BUS INTernal
Explanation  This command is only applicable to the burst (N cycle, infinite or gated) output
or sweep output.
 The N cycle burst and sweep mode support internal trigger. When internal
trigger is selected, the frequency of the N cycle burst is determined by the
“Burst Period” and the trigger period of the sweep waveform is determined by
the specified sweep time, return time, start hold and stop hold. 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 type (rising edge or
falling edge) or turn off the trigger signal output.
 The N cycle, infinite and gated bursts as well as the sweep mode all supports
external trigger. When external trigger is selected, 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 burst (N cycle, infinite or
gated) output or sweep output each time a TTL pulse with the specified polarity
is received. You can specify the edge type of the trigger input signal
( :TRIGger[<n>]:SLOPe ).
 The N cycle and infinite bursts as well as the sweep mode support manual
trigger. When manual trigger is selected and the output of the corresponding
channel is turned on, the instrument outputs N cycle burst or infinite burst
when the *TRG , :TRIGger[<n>][:IMMediate] or
[:SOURce[<n>]]:BURSt:TRIGger[:IMMediate] command is sent; the
instrument initiates a sweep in the corresponding channel immediately each
time the *TRG , :TRIGger[<n>][:IMMediate] or
[:SOURce[<n>]]:SWEep:TRIGger[:IMMediate] command is send. If the output
of the corresponding channel is not turned on, the trigger will be ignored. 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 type
(rising edge or falling edge) or turn off the trigger signal output.
 When [<n>] is omitted, the system sets the related parameters of CH1 by
default.
Return Format The query returns INT, EXT or MAN.
Example :TRIG1:SOUR INT /*Set the trigger source of CH1 to internal*/
:TRIG1:SOUR? /*Query the trigger source p of CH1 and the query returns
INT*/
