SA (Spectrum Analyzer) Mode (Option 233–Mixed Analyzers)
SA Mode Settings
—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.
Oversweep
In SA mode, the FieldFox uses Oversweep to quickly analyze input signals.
Oversweep is meant to verify that your setup is correct, but Oversweep is not
meant to be as accurate as FFT and Step sweeps. See also, “How to set Sweep
Type” on page 182.
How to set Oversweep
—Press BW 2 > Advanced then
—Press Oversweep
– To enable/disable the Oversweep. Over sweep enables
you to quickly evaluate your setup.
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 “Right Side Panel” on page 39.
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 Meas UNCAL appears on the screen to indicate this. Learn more
in “Individual Alignments” on page 200.
