Frequency/Span/Step

Valid CPM 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

which power is detected and displayed. The maximum measurement span is

A Radio Standard can also be used to set the center frequency and span. Learn
