Turns off the sync source for your periodic trigger. With the sync source off, the timing will drift unless
the signal source frequency is locked to the analyzer frequency reference.

External 1
Pressing this key, when it is not selected, selects the external input port that you will use for the periodic
trigger synchronization. Pressing this key, when it is already selected, accesses the external 1 sync source

Trigger Level
Sets the value where the signal at the external 1 trigger input will synchronize with the periodic timer trigger. This
same level is used in the Ext1 trigger source in the Trigger menu. See section
information on this key and the SCPI command.
Trig Slope
Controls the trigger polarity. It is set positive to trigger on a rising edge and negative to trigger on a falling edge.
This same value is used in the Ext1 trigger source in the Trigger menu. See section
information on this key and the SCPI command
External 2
Pressing this key, when it is not selected, selects the external input port that you will use for the periodic
frame trigger synchronization.
Pressing this key, when it is already selected, accesses the external 2 sync source setup menu.

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.
