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

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.
