[:SOURce]:RADio:CUSTom:TRIGger[:SOURce]?
This command sets the trigger source.
For more information on triggering, see “:TRIGger:TYPE” on page 402. The following list describes the
command choices:
KEY This choice enables manual triggering by pressing the front-panel Trigger hardkey.
EXT
An externally applied signal triggers the waveform. This is the only choice that works
with gating. The following conditions affect an external trigger:
• The input connector selected for the trigger signal. You have a choice between the
rear-panel PATTERN TRIG IN connector or the PATT TRIG IN 2 pin on the
rear-panel AUXILIARY I/O connector. To make the connector selection, see
“:TRIGger[:SOURce]:EXTernal[:SOURce]” on page 406.
For more information on the connectors and on connecting the cables, see the
User’s Guide.
• The trigger signal polarity:
— gating mode, see “:TRIGger:TYPE:GATE:ACTive” on page 403
— continuous and single modes, see “:TRIGger[:SOURce]:EXTernal:SLOPe” on
page 405
• The time delay between when the signal generator receives a trigger and when the
waveform responds to the trigger. There are two parts to setting the delay:
— setting the amount of delay, see “:TRIGger[:SOURce]:EXTernal:DELay” on
page 404
— turning the delay on, see “:TRIGger[:SOURce]:EXTernal:DELay:STATe” on
page 405
BUS This choice enables triggering over the GPIB or LAN using the *TRG or GET
commands or the AUXILIARY INTERFACE (RS- 232) using the *TRG command.
*RST
KEY
:TRIGger[:SOURce]:EXTernal:DELay
Supported N5172B/82B with Option 431
[:SOURce]:RADio:CUSTom:TRIGger[:SOURce]:EXTernal:DELay <val>
[:SOURce]:RADio:CUSTom:TRIGger[:SOURce]:EXTernal:DELay?
This command sets the number of bits to delay the signal generator’s response to an external trigger.
