Triggering the Sweep – TRIG Key
The TRIG key opens a menu for selection of the various trigger sources, trigger polarity and external
gate function. The active trigger mode is indicated by highlighting the corresponding softkey.
For video trigger, a trigger threshold can be entered, which is represented in the diagram as a horizontal
line.
To indicate that a trigger mode other than FREE RUN has been set, the enhancement label TRG is
displayed on the screen. If two windows are displayed, TRG appears next to the appropriate window.
The option TV and RF Trigger (R&S FSP-B6) adds a number of trigger functions for the analysis of TV
signals to this menu (see section Option FSP-B6 – TV and RF Trigger, page 4.100).
