Trigger
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 “Trigger Level ” on page 1354 for
information on this key and the SCPI command.
Trig S lope
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 “Trig Slope ” on page 1355 for
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.
Trigger Level
Sets the value where the signal at the external 2 trigger input will synchronize with the periodic timer trigger. This
same level is used in the Ext2 trigger source in the Trigger menu. See section “Trigger Level ” on page 1357 for
information on this key and the SCPI command.
Trig S lope
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 Ext2 trigger source in the Trigger menu. See section “Trig Slope ” on page 1358 for
information on this key and the SCPI command
RF Burst
Pressing the key once selects the RF burst envelope signal to be used for the periodic timer trigger
synchronization.
Press the key a second time to access the RF burst sync source setup menu.
Key Path: Trigger, Periodic Timer, Sync Source
Example: TRIG:FRAM:SYNC EXT2
Dependencies: 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.
Couplings: Same as External 2 trigger source.
