The frequency of the source can be specified by a channel number of a given
frequency band. This control allows you to specify the current channel number. For
the appropriate range of channel numbers for a given frequency band, see the
following tables: "GSM/EDGE Channel Number Ranges" on page 1959, "W-CDMA
Channel Number Ranges" on page 1960, "LTE FDD Channel Number Ranges" on
page 1961, and "LTE TDD Channel Number Ranges" on page 1963.

Couplings The channel number is coupled to the frequency value when "Radio Standard/Radio Band" on page
1964 is not set to NONE
When the frequency value is changed, the channel number increases or decreases to match the new
frequency. If the frequency is not at an exact match for a channel number, the nearest channel number
is displayed, with > or < indicating whether the frequency is above or below the channel number
