To indicate that a gate is used for the sweep, "GAT" and the gate source is displayed in
the channel bar.
Gated measurements in receiver application
Gated measurements are also available in the receiver application. Basically, they
work like gated measurements in the spectrum application with some distinctive fea-
tures.
In the receiver application, a gated measurement affects the bargraph, scan and final
measurement. They are useful, for example, when you only want to collect measure-
ment data during times when a DUT is actually running and emits potential interfering
signals, or in case you already know that interferers occur regularly and want to collect
measurement data during the time when the interference is not present.
The following distinctive features apply.
●
The scan is interrupted when the gate is closed. When it reopens, the scan is
resumed on the last measured frequency (just like if you have interrupted the scan
deliberately).
●
Each measurement point is measured for a certain period of time (defined by the
). If the gate closes before the R&S
ESW is done with any par-
ticular measurement point, the remaining time is measured when the gate opens
again. The actual results in that case are the sum of the partial measurements.
Example
: The measurement time is 1 second. The gate closes after 0.6 seconds.
The data that has already been collected is kept. When the gate opens again, the
R&S
ESW resumes the measurement for another 0.4 seconds, and combines the
two partial measurements.

Additional trigger ports
The R&S
ESW provides three trigger ports. One exclusively serves as a trigger input,
while you can configure the other two trigger ports to be a trigger output as well.
