Test Descriptions

Input VSWR

NOTE • denotes test required for associated model number.

NOTE The NFA uses several frequency dependent paths within the front end

assemblies to cover its operating range. It is therefore not possible to

complete a single VSWR swept measurement at a single fixed frequency

point over its entire operating range, as the NFA automatically switches

at approximately 500 MHz and 3000 MHz, dependant on the fixed

frequency setting.
