Frequency Range

The X-axis frequency range determines the frequencies that are measured for
each sweep. The default Start frequency is 0 Hz. 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. Below 9 kHz, frequency accuracy is
maintained, but amplitude accuracy is degraded.
The FieldFox can be used with an OML frequency extender. Refer to
"Utilities" on page
5992-3701EN, and to
Available ONLY with Opt. 209 and while in Step sweep, SA mode allows reverse
sweeps. This means the Start frequency can be higher than the Stop
frequency. In addition, the Reverse Swap feature can be used to quickly
reverse the Start and Stop frequencies. Learn how in

The frequency range of the measurement can be changed using the following
methods:
— Set Center and Span frequencies
— Set Start and Stop frequencies
— Toggle between Zero and Last selected span
— Set Full Span of the FieldFox
— Using Channel selection. Learn how in
— Using Marker -> Center (frequency). Learn how in
