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 8.6.1.3, "How to Deter-
mine the Required Trigger/Gate Parameters"
2. The gate is opened by a trigger event, which must be 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 "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".
b) Define the time to measure for each gate: "Gate Length".
4. To open the gate with a time delay, for example to ignore an overshoot, define a
"Gate Delay".
5. Select "Gated Trigger" = "On".
To configure a continuous gated measurement
A continuous gated measurement is based on a common gated measurement. How-
ever, after a single external trigger event, multiple further gate measurements are per-
formed.
1. The gate is opened by a trigger event, which must be provided by an external trig-
ger source. Define the trigger as described in
Chapter 8.6.1.4, "How to Configure a
on page 486. As the "Trigger Source", use "External".
2. In the "Gate Settings" of the "Trigger and Gate" dialog box, select "Gated Trigger":
"On".
3. Define the gate settings as described in
"To configure a common gated measure-
4. Select the "Cont. Gate" tab next to the "Gate Settings".
5. Set "Continuous Gate" to "On".
