3.4.1 Scenario Start Variations
Hold before manual start
Once you pressed start , or enter (with the Start main menu option highlighted), the GSG unit
requires some time to launch the scenario (the delay depends on the size/complexity of the
scenario data).
During this wait time, press the [.] (hold) key if you want to prevent the scenario from beginning
to run before you are ready. This is called "
arming"
(the
ARM
text icon will display in the
upper right corner of the display, and the armed status indicator will light up).
Once you are ready, press the start key to run the armed scenario.
SCPI START command
Once you submitted the SCPI command
SOURce:SCENario:LOAD
, submit another com
mand to arm the GSG simulator:
SOURce:SCENario:CONTrol ARM
.
Then, to start scenario execution, submit the SCPI start command:
SOURCce:SCNario:CONTrol START
.
Start via external trigger
After arming a loaded scenario (see above), the scenario execution can be started via an
external trigger signal, submitted to the GSG unit by means of the BNC input (see "External
Trigger Input" under "Rear Panel Outputs and Inputs" on page 8).
3.4.2 Scenario Execution Views
While a scenario is running (also referred to as "scenario execution"), you can display several
views, so as to …
monitor the current scenario status
verify the operation of your receiver-under-test by comparing its output with the data
provided in the scenario execution views
adjust some of the scenario settings.
