Agilent X-Series Signal Generators SCPI Command Reference 271
Arb Commands
Dmodulation Subsystem–N5172B/82B with Option 431 ([:SOURce]:RADio:DMODulation:ARB)
For setting the delay time, see “:TRIGger[:SOURce]:EXTernal:DELay” on page 270, and for more
information on configuring an external source, see“:TRIGger[:SOURce]” on page 269.

:TRIGger[:SOURce]:EXTernal:SLOPe
Supported N5172B/82B with Option 431
[:SOURce]:RADio:DMODulation:ARB:TRIGger[:SOURce]:EXTernal:SLOPe POSitive|NEGative
[:SOURce]:RADio:DMODulation:ARB:TRIGger[:SOURce]:EXTernal:SLOPe?
This command sets the polarity for an external trigger signal while using the continuous, single
triggering mode. To set the polarity for gating, see “:TRIGger:TYPE:GATE” on page 269.
The POSitive and NEGative selections correspond to the high (positive) and low (negative) states of
the external trigger signal. For example, when you select POSitive, the waveform responds (plays)
during the high state of the trigger signal. When the X- Series signal generator receives multiple
trigger occurrences when only one is required, the signal generator uses the first trigger and ignores
the rest.
For more information on configuring an external trigger source and to select external as the trigger
source, see “:TRIGger[:SOURce]” on page 269.

:TRIGger[:SOURce]:EXTernal[:SOURce]

EPT1|EPT2|EPTRIGGER1|EPTRIGGER2
[:SOURce]:RADio:DMODulation:ARB:TRIGger[:SOURce]:EXTernal[:SOURce]?
This command selects which PATTERN TRIG IN connection the X- Series signal generator uses to
accept an externally applied trigger signal when external is the trigger source selection.
For more information on configuring an external trigger source and to select external as the trigger
source, see “:TRIGger[:SOURce]” on page 269. For more information on the rear panel connectors, see
the User’s Guide.
The following list describes the command choices:
EPT1 This choice is synonymous with EPTRIGGER1 and selects the PATTERN TRIG IN
rear panel connector.
EPT2 This choice is synonymous with EPTRIGGER2 and selects the PATT TRIG IN 2 pin
on the rear panel AUXILIARY I/O connector.
EPTRIGGER1 This choice is synonymous with EPT1 and selects the PATTERN TRIG IN rear
panel connector.
EPTRIGGER2 This choice is synonymous with EPT2 and selects the PATT TRIG IN 2 pin on the
rear panel AUXILIARY I/O connector.
