Sweep/Control
Gated FFT cannot be done in zero span since the instrument is not sweeping. So in zero span the
Gated LO method is used. Data is still only taken while the gate conditions are satisfied, so the
gate settings do impact when data is acquired.
The Gate Length will be 1.83/RBW.
This is a convenient way to make a triggered FFT measurement under control of an external
gating signal.
Key Path Sweep/Control, Gate
Dependencies Key is unavailable when Gate is On and Swept Sweep Type is manually selected.
Key is unavailable when gate Control is set to Level.
When selected, Sweep Type is forced to FFT and the Swept key in Sweep Type is grayed out
Forces Gate Length to 1.83/RBW

Gate Source
The menus under the Gate Source key follow the same pattern as those under the Trigger key, with
the exception that neither Free Run nor Video are available as Gate Source selections. Any changes
to the settings in the setup menus under each Gate Source selection key (for example: Trigger Level)
also affect the settings under the Trigger menu keys. Note that the selected Trigger Source does not
have to match the Gate Source.

Dependencies In some models, there is no second External input. In these models, the External 2 key is
blanked and the EXTernal2 parameter will generate a “Hardware missing; Not available for this
model number” error.

Backwards Compatibility
Notes In ESA, there is a single Gate input port. In PSA, the Gate Source may be taken from one of two
specified input ports. In the X-Series, any Trigger Source can be a Gate Source.
