8.6.10 Configuring Gated Measurements
Usually in spectrum analysis, measurements are based on a certain length of time
called the gate area. With I/Q gating, you can define the gate area using the gate
length, the distance between the capture periods and the number of periods. The gate
length and the distance between the capture periods are specified in samples.
I/Q gating is only available using remote commands; manual configuration is not possi-
ble.
Using I/Q gating, the gate area can be defined using the following methods:
●
Edge triggered capturing
After a trigger signal, the gate period is defined by a gate length and a gate dis-
tance. All data in the gate period is captured until the required number of samples
has been captured.
