13 Modulation Accuracy (Composite EVM) Measurement
Source
Trigger Source
Allows access to the trigger source sub-menus. The trigger source setting determines how the source
receives the trigger that starts the waveform playing. Therefore, this key is grayed out if the trigger type is
free run, since free run triggers immediately with no trigger source required.
Key Path
Source, Modulation Setup, ARB
Remote Command
:SOURce:RADio:ARB:TRIGger[:SOURce] KEY|BUS|EXTernal2
:SOURce:RADio:ARB:TRIGger[:SOURce]?
Example
:SOUR:RAD:ARB:TRIGger KEY
Dependencies
This key is grayed out if the current trigger type is Continuous, Free Run.
Preset
EXTernal2
Range
Trigger Key | Bus | External 2
Initial S/W Revision
A.05.00
Trigger Key
Sets the current trigger source to the front panel Trigger key. When Trigger Key is selected, the waveform
is triggered when you press the front panel Trigger key.
Key Path
Source, Modulation Setup, ARB, Trigger Source
Example
:SOUR:RAD:ARB:TRIGger KEY
Initial S/W Revision
A.05.00
Bus
Sets the current trigger source to Bus. Selecting Bus trigger source enables triggering over GPIB, LAN, or
USB using the :SOURce:RADio:ARB:TRIGger:INITiate command.
Key Path
Source, Modulation Setup, ARB, Trigger Source
Example
:SOUR:RAD:ARB:TRIGger BUS
Initial S/W Revision
A.05.00
External 2
Sets the current trigger source to External 2. Selecting External 2 enables triggering a waveform by an
externally applied signal.
Key Path
Source, Modulation Setup, ARB, Trigger Source
Example
:SOUR:RAD:ARB:TRIGger EXT2
Notes
Note: When on E6640A, trigger 2 is a bi-directional trigger port. So when trigger 2 has been
configured as OUTPUT type, choosing External 2 as the input trigger for the current step will
generate error.
