Because there is no calibration, these settings can be made in any order.

How to select RTSA Mode

When you initially select I/Q Analyzer, Real-Time SA, or some of the other
spectrum settings (such as center
measurement is applied to the signal. During channel equalization
measurement, the FieldFox displays a "Start Channel Equalization".
Stopping channel equalization is not permitted. See also,
page
Analyzers)."

Frequency Range

The X-axis frequency range determines the frequencies that are measured for
each sweep. The default Start frequency is 995 MHz. However, the Start
frequency can be set as low as –100 MHz. The internal LO of the FieldFox can
be seen at 0 Hz, which will mask signals that may be present.
Although the start frequency can be set as low as -100 MHz, amplitude
accuracy is specified above 9 kHz to 100 kHz (depending on your model).
Below 9 kHz to 100 kHz (depending on model), frequency accuracy is
maintained, but amplitude accuracy is degraded. Refer to
https://www.keysight.com/us/en/assets/7018-03314/data-sheets/5990-
9783.pdf.
The FieldFox can be used with an OML frequency extender. Refer to
"Utilities" on page
5990-9836EN, and to
The frequency range of the measurement can be changed using the following
methods:
— Set Center and Span frequencies (Freq Span is settable from 280 Hz to
— Set Start and Stop frequencies
— Toggle between Zero and Last selected span
— Using Marker -> Center
