:TRIGger Commands 35

Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 1329

:TRIGger[:EDGE]:SOURce

(see page 1610)

Command Syntax

:TRIGger[:EDGE]:SOURce <source>

<source> ::= {CHANnel<n> | EXTernal | LINE | WGEN | WGEN1 | WGEN2

| WMOD} for the DSO models

<source> ::= {CHANnel<n> | DIGital<d> | EXTernal | LINE | WGEN | WGEN1

| WGEN2 | WMOD} for the MSO models

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

<d> ::= 0 to (# digital channels - 1) in NR1 format

Note: WAVE and WGEN1 are equivalent.

Note: WGEN2 only available on models with 2 WaveGen outputs.

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, WGEN1, WGEN2 — triggers at the 50% level of the rising edge of the

waveform generator output signal. This option is not available when the DC,

NOISe, or CARDiac waveforms are selected.

• WMOD — when waveform generator FSK or FM modulation is used, triggers at

the 50% level of the rising edge of the modulating signal.

Query Syntax

:TRIGger[:EDGE]:SOURce?

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

off, the query returns "NONE."

Return Format

<source> ::= {CHAN<n> | EXT | LINE | WGEN | WGEN1 | WGEN2 | WMOD

| NONE} for the DSO models

<source> ::= {CHAN<n> | DIG<d> | EXTernal | LINE | WGEN | WGEN1

| WGEN2 | WMOD | NONE} for the MSO models

Example Code

' TRIGGER_EDGE_SOURCE - Selects the channel that actually produces th

' edge trigger. Any channel can be selected.

myScope.WriteString ":TRIGger:EDGE:SOURce CHANnel1"
