Gates can be used in two different modes:
●
Level:
The gate opens and the measurement starts when a defined level in the
gate source is exceeded and stops when the gate source drops below the "Gate
Level".
Using a pulsed gate signal in level mode, the following behavior can be achieved:
When the gate source signal is active, the input signal data is collected; when the
gate signal is inactive, the input signal is ignored.
●
Edge:
The gate opens and the measurement starts when a defined level in the
gate source is exceeded and stops when the defined "Gate Length" is reached.
Additionally, a delay time can be defined so that the first few measurement points after
the gate opening are ignored.
To indicate that a gate is used for the sweep, "GAT" and the gate source is displayed in
the channel bar.

Gate Settings
Access
: "Overview" > "Trigger" > "Trigger / Gate Config." > "Gate Settings"
Gate settings define one or more extracts of the signal to be measured.
Gating is not available for measurements on I/Q-based data.
Gated Trigger
Switches gated triggering on or off.
If the gate is switched on, a gate signal applied to one of the TRIGGER INPUT connec-
tors or the internal IF power detector controls the sweep.
