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.
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 “Reverse Swap” on
page 115.
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 “Channel Selection” on page 113.
Using Marker -> Center (frequency). Learn how in “SA Marker Functions”
on page 204.
How to set Frequency Range
—Press Freq/Dist.
Then choose from the following:
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 222, the B Series FieldFox Configuration Guide
5992-3701EN, and to “Contacting Keysight” on page 5.
