External 2

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 2 input
connector. The external trigger 2 input connector is on the rear panel.
Pressing this key, when it is already selected, accesses the external 2 trigger setup menu.

For backward compatibility, EXTernal should also work.
Also, there are DELay backward compatibility commands described in video
section "Trig Delay " on page 578
:TRIGger[:SEQuence]:DELay
Also, the legacy ESA command for trigger offset,
TRIGger[:SEQuence]:OFFSet, is supported (see section
(Remote Command Only)" on page
commands is remembered by the analyzer and added to the external1 trigger
delay whenever the value is sent to the hardware, when in zero span and in a

In some models, there is no second External input. In these models, the
External 2 key is blanked and the EXTernal2 parameter will generate a
"Hardware missing; Not available for this model number" message.

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.
