Using IQ Gating
IQ gating refers to recording IQ samples in certain time intervals – the gate areas.
There are different modes to define the gate areas:
●
Edge triggered recording
●
Level triggered recording
For more information, see "IQ Gating" in the "Remote Commands" chapter under
"Trace:IQ" subsystem.
Measurement example: Level mode
With IQ gating in level mode, the area in which the gate signal is active is recorded. In
this example, the gate signal is generated by the IFP trigger. The
shows
the signal (triggered externally) in IQ mode. The following sample program records the
signal in level mode with an external trigger.

Used values
sample rate: 32 MHz
number of IQ samples: 128000
trigger mode: IFP
