6.7 Trigger and Gate Configuration
Triggering means to capture the interesting part of the signal. Choosing the right trigger
type and configuring all trigger settings correctly allows you to detect various incidents
in your signals.
Gating allows you to restrict measurement analysis to the important part or parts of the
signal, for example bursts.

6.7.1 Triggering
6.7.1.1 Triggered Measurements
In a basic measurement with default settings, the sweep is started immediately. How-
ever, sometimes you want the measurement to start only when a specific condition is
fulfilled, for example a signal level is exceeded, or in certain time intervals. For these
cases you can define a trigger for the measurement. In FFT sweep mode, the trigger
defines when the data acquisition starts for the FFT conversion.
An "Offset" can be defined to delay the measurement after the trigger event, or to
include data before the actual trigger event in time domain measurements (pre-trigger
offset).
