8.3 Gate Settings
8.3.12 Gate Preset (Remote Command Only)
Presets the time-gated spectrum analysis capability.
This command sets gate parameter values to the ESA preset values, as follows:
–
Gate trigger type = edge
–
Gate polarity = positive
–
Gate delay = 1 us
–
Gate length = 1 us

8.3.13 Gate Level (Remote Command Only)
Sets the gate input transition point level for the external TRIGGER inputs on the
front and rear panel. This is a legacy command for PSA compatibility. It is simply an
alias to the equivalent trigger level command.
Notes This command is simply an alias to
:TRIGger[:SEQuence]:EXTernal[1]|2:LEVel

8.3.14 Gate Polarity (Remote Command Only)
Sets the polarity for the gate signal. This setup is now done using the gate trigger’s
slope setting.
When POSitive is selected, a positive-going edge (Edge) or a high voltage (Level)
will satisfy the gate condition, after the delay set with the Gate Delay key. When
NEGative is selected, a negative-going edge (Edge) or a low voltage (Level) will
satisfy the gate condition after the delay.

:SWE:EGAT:POL NEG
:SWE:EGAT:POL?
