Select RTSA Mode before making any setting in this chapter.
Because there is no calibration, these settings can be made in any order.
How to select RTSA Mode

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.
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
10 MHz)
— Set Start and Stop frequencies
— Using Marker -> Center
How to set Frequency Range
— Press
Freq/Dist
.
— Then choose from the following:
—
Center
and
Freq Span
frequencies. This is the most common method
of entering frequency range. Enter the frequency of interest. The
Center frequency is at the exact center of the X-axis. The Frequency
Span places half of the frequency range on either side of center.
When you initially select I/Q Analyzer, Real-Time SA, or some of the other
spectrum settings (such as center frequency) a factory channel
Equalization ment is applied to the signal. During channel equalization
ment, the FieldFox displays a "Start Channel Equalization". Stopping
channel equalization is not permitted. See also,
Chapter 9, “SA (Spectrum Analyzer) Mode.”
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
