Gate Length ← Gate Settings
Defines how long the gate is open when it is triggered. The gate length can only be set
in the edge-triggered gate mode. In the level-triggered mode the gate length depends
on the level of the gate signal.
The gate length in relation to the sweep is indicated by a line labeled "GL".
For more information see chapter 6.6.1.2, "Gated Measurements", on page 422

6.6.3 How to Configure a Triggered and Gated Measurement
The following step-by-step instructions demonstrate how to configure a triggered and
gated measurement manually. For remote operation see chapter 11.7.4, "Configuring
Triggered and Gated Measurements", on page 850.
Trigger and gate settings are configured in the "Trigger and Gate" dialog box.
To display the "Trigger and Gate" dialog box, do one of the following:
●
Select "Trigger/Gate" from the "Overview".
●
Select the TRIG key and then the "Trigger/Gate Config" softkey.
The following tasks are described:

6.6.3.1 How to Determine the Required Trigger/Gate Parameters
1. In the "Trigger and Gate" dialog box, switch on "Show Preview".
A zero span measurement for the currently defined center frequency is displayed.
2. Set the "Frequency", "RBW" and "Sweep Time" such that the relevant part of the
signal is displayed, for example a complete burst.
3. Determine the parameters you want to use to define the trigger and gate conditions
from the preview diagram, for example:
● the length of a burst or slot
● the upper or lower power level of a pulse
● the maximum noise level
● the power level or time at which a certain incident occurs
4. Try out different trigger and gate settings as described in How to Configure a Trig-
gered Measurement and How to Configure a Gated Measurement, then select
"Update Main Diagram" to see the effect of the current settings on the main mea-
surement in the background.
