on page 776
Gate Mode
Sets the gate mode.
For more information see Chapter 6.7.2.1, "Gated Measurements" , on page 343
Remote command:

Gate Delay
Defines the delay time between the gate signal and the continuation of the measure-
ment.
The delay position on the time axis in relation to the sweep is indicated by a line
labeled "GD".
For more information see Chapter 6.7.2.1, "Gated Measurements" , on page 343

Gate Length
Defines how long the gate is open when it is triggered.
The gate length in relation to the sweep is indicated by a line labeled "GL".

6.7.2.3 How to Configure a Gated Measurement
A gated measurement records data only while the gate conditions are fulfilled. These
step-by-step instructions demonstrate how to configure a gated measurement man-
ually.
To configure a common gated measurement
1. Determine the required parameters as described in Chapter 6.7.1.3, "How to Deter-
mine the Required Trigger/Gate Parameters" , on page 342.
2. The gate is opened by a trigger event, which must be based on a power source.
Define the trigger as described in Chapter 6.7.1.4, "How to Configure a Triggered
Measurement" , on page 343. As the "Trigger Source", use "IF Power", "Video" or
"External".
3. Define how long the gate is to remain open:
To measure the signal as long as the trigger level is exceeded, for example for one
or more pulses, define "Gate Mode" = "Level".
To measure the signal for a certain time after a level is exceeded, for example dur-
ing a burst:
a) Define "Gate Mode" = "Edge".
