IF Output

The FieldFox IF (intermediate frequency) can be output for external signal
processing. The signal is available from the IF Out connector on the FieldFox
right-side panel. See the connector in
The IF Out signal, centered at approximately 33.75 MHz, is simply a
down-converted version of the RF Input signal that is present at the tuned
frequency.
While outputting an IF signal, the FieldFox stops performing the InstAlign
process. Therefore, the amplitude of traces on the FieldFox screen is NOT
accurate and

How to select IF Output
The IF Output signal is useful only in Zero Span. Learn more about Zero Span in

At least one sweep must be made in order to tune the FieldFox.

Keysight N9927-90001 User's Guide
—Auto The FieldFox selects the most efficient sweep type based on the
Res BW. When Res BW is set to 200 kHz and below, FFT sweep type
is selected. Above 200 kHz, Step sweep type is being performed.
—FFT The FieldFox uses FFT sweep type regardless of the Res BW.
—Step The FieldFox uses Step sweep type regardless of the Res BW.
This is useful for capturing impulsive noise that may be generated
from nearby electrical equipment.
