Radio standards
With a radio standard applied, pre-defined frequency bands, channel numbers or uplink / downlink selections can be used instead of
manual frequency entry. The pre-defined FieldFox radio standards include bands such as W-CDMA, LTE, and GSM. Alternately, users
can create custom standards and import them into FieldFox analyzers.
