Configuring I/Q Gating
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.
●
Level triggered capturing
After a trigger signal, all data is captured in which the gate signal is set to 1, which
means it has exceeded a level. In this case, the gate signal can be generated by
the IFP trigger, for example: each time the IFP level is exceeded, the IFP trigger
signal is set to 1 and the samples in this area are captured as gate samples.
The number of complex samples to be captured prior to the trigger event can be
selected (see
on page 197) for all available trigger sources, except
for "Free Run".
