Comments • The sources available are:
– BUS: The Group Execute Trigger (GET) GPIB command or the IEEE-488.2
*TRG common command.
– ECLTrg0 and ECLTrg1: The VXIbus ECL trigger lines.
– EXTernal: The Agilent E1445A’s front panel “Ref/Sample In” BNC connector.
– HOLD: Suspends sample generation. Use the TRIGger[:STARt][:IMMediate]
command to advance the waveform.
– INTernal[1]: The [SOURce:]FREQuency[1] subsystem. Sine wave output
(
[SOURce:]FUNCtion[:SHAPe] SINusoid set) requires that this source be selected.
– INTernal2: The [SOURce:]FREQuency2 subsystem.
– TTLTrg0 through TTLTrg7: The VXIbus TTL trigger lines.
• Use the TRIGger[:STARt]:SLOPe command to select the active edge for the front
panel “ Ref/Sample In” BNC when used as the start trigger source.
• Executable when Initiated: No
• Coupling Group: Frequency
• Related Commands: TRIGger[:STARt]:SLOPe
•
*RST Condition: TRIGger:STARt:SOURce INTernal1
Example Setting the Start Trigger Source
TRIG:SOUR EXT Trigger source is front panel’s “Ref/Sample
In” BNC.
