(see page 798)

Command Syntax

:TRIGger[:EDGE]:SOURce <source>

<source> ::= {CHANnel<n> | EXTernal | LINE | WGEN}

<n> ::= 1 to (# analog channels) in NR1 format

The :TRIGger[:EDGE]:SOURce command selects the input that produces the

trigger.

• EXTernal — triggers on the rear panel EXT TRIG IN signal.

• LINE — triggers at the 50% level of the rising or falling edge of the AC power

source signal.

• WGEN — triggers at the 50% level of the rising edge of the waveform generator

output signal. This option is not available when the DC or NOISe waveforms are

selected. This option is also not available when serial decode is on due to

hardware limitations.

The :TRIGger[:EDGE]:SOURce? query returns the current source. If all channels are

off, the query returns "NONE."
