6.6.1.3
Determining the Parameters in Preview Mode
The preview mode allows you to try out trigger and gate settings before actually apply-
ing them to the current measurement. When the preview diagram shows the correct
results, you can "Update the Main Diagram" and check the results in the background
before closing the dialog box.
If preview mode is switched off, changes to the trigger and gate settings are applied to
the measurement diagram directly.
The preview diagram displays a zero span measurement at the center frequency with
the defined RBW and sweep time. This is useful to analyze bursts, for example, to
determine the required gate settings. The main diagram remains unchanged concern-
ing the zero span settings. Only the trigger and gate settings are applied to the mea-
surement.
6.6.2 Trigger and Gate Settings
Trigger and gate settings can be configured via the TRIG key or in the "Trigger and
Gate" dialog box, which is displayed when you select the "Trigger/Gate" button in the
"Overview".
External triggers from one of the TRIGGER INPUT/OUTPUT connectors on the
R&S
FSW are configured in a separate tab of the dialog box.
