Frequency/ Span / Step
Valid Built-in Power Meter measurements can be made over the entire
frequency range of the FieldFox. Although it is possible to enter a center
frequency below the FieldFox minimum frequency, the LO feed-thru of the
internal SA hardware will invalidate these Built-in Power Meter measurements.
The measurement span (also known as Channel Width and Integration BW) is
the frequency range, half above and half below the center frequency, over
which power is detected and displayed. The maximum measurement span is
100 MHz.
How to enter center frequency, step size, and span
The default frequency is 50 MHz.
— Press Freq/Dist
