Remote commands to trigger measurements:
●
It often makes sense to capture data only when interesting events occur in the spec-
trum or only capture parts of a signal. In such cases, you can use a trigger. A trigger
responds to certain events. When you use a trigger, the analyzer starts a measure-
ment only when certain trigger conditions are met.
Selecting the trigger source
The trigger source selects the type of event whose condition must be met to start data
acquisition.
1. Press the "Sweep" key to open the sweep menu.
2. Select the "Trigger" menu item to open the trigger menu.
3. Select one of the trigger sources.
● "Free Run"
No trigger source is considered. You can start the measurement manually any
time and stop it as required.
● "Video Trigger"
A measurement starts when the voltage of the video signal exceeds a certain
level.
When you select the video trigger, the R&S
FPC1000 opens an input field to
define the trigger level that the video signal must meet or exceed. The video
trigger level is a percentage of the diagram height (0
% to 100
%). A small sym-
bol on the diagram's y-axis ( ) indicates the absolute trigger level.
