6. Define the length in seconds from the beginning of one gate measurement to the
beginning of the next one ("Gate Period Length").
7. Define how many gate measurements are to be performed after a single trigger
event ("Gate Period Count").
8. Run a measurement and wait for the external trigger event to occur.
To configure a triggered gated measurement
A triggered gated measurement is based on a common gated measurement. However,
the gates are only opened after an initial trigger event.
1. Determine the required parameters as described in
Chapter 8.6.1.3, "How to Deter-
mine the Required Trigger/Gate Parameters"
2. In order to trigger the initial gate, define a trigger event based on a power source.
Define the trigger as described in
Chapter 8.6.1.4, "How to Configure a Triggered
on page 486. As the "Trigger Source", use "External" or "Power
Sensor" (if available).
3. Each individual gate is also opened by a trigger event. To use a different trigger
source for the individual gates than for general measurement:
a) Switch to the "Source" tab for gate settings.
b) As the "Source", select "External" or "Power Sensor" (if available).
c) Configure the power trigger as defined in
Chapter 8.6.1.4, "How to Configure a
4. Switch to the "Gate Settings" tab to define the individual gates.
5. 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".
b) Define the time to measure for each gate: "Gate Length".
6. To open the gate with a time delay, for example to ignore an overshoot, define a
"Gate Delay".
7. Select "Gated Trigger" = "On".

Some settings can be adjusted by the R&S
FSW automatically according to the current
measurement settings. In order to do so, a measurement is performed. You can config-
