Set Frequency/Span; Radio Standard - Keysight N9912A User Manual

CAUTION
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 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.
A Radio Standard can also be used to set the center frequency and span. Learn more
about Radio Standards on page 70.

Radio Standard

A Radio Standard can used to integrate power within specific radio channels. When a
Radio Standard is selected, the Span setting is automatically coupled to the defined
Channel Width for that standard. (Width is the same for all channels within a
standard.) Also, Unit is set to Chan and CF is set to the nearest specific Channel
defined in the standard.
Learn all about Radio Standards, including Importing and Deleting Custom Radio
Standards, beginning on page 70.

Span (Ch Wid)
press a multiplier key. The default span is 2 MHz. The maximum measurement
span is 100 MHz. The current span setting is shown as the dividend in the digital
display. For example: -10 dBm / 1.00 MHz
