Trigger
External 1
Pressing this key, when it is not selected, selects an external input signal as the trigger. A new
sweep/measurement will start when the external trigger condition is met using the external 1 input
connector on the rear panel.
Pressing this key, when it is already selected, accesses the external 1 trigger setup menu.
Trigger Level
Sets the value where the external 1 trigger input will trigger a new sweep/measurement.
Backwards Compatibility Notes: The legacy :TRIGger[:SEQuence]:DELay command affects the delay for the
VID, LINE, EXT1, EXT2, and RFB triggers.
The legacy :TRIGger[:SEQuence]:OFFSet command is supported for the
VIDeo, LINE, EXT1, and EXT2 triggers.

Status Bits/OPC dependencies: The Status Operation Register bit 5 "Waiting for Trigger" is set at the same
time as the Sweeping or Measuring bit is set. It is cleared when the trigger
actually occurs (that is, after the trigger event occurs and all the applicable
trigger criteria have been met). A corresponding pop-up message ("Waiting
for trigger") is generated if no trigger signal appears after approximately 2 sec.
This message goes away when a trigger signal appears.
