The microwave combination analyzer's base function is a cable and antenna analyzer and it can be configured to include a spectrum and network analyzer. FieldFox can be ordered with additional capabilities: power meter, independent signal generator, vector voltmeter, interference analyzer, variable DC source, built-in GPS receiver, and remote control using an iPad or iPhone. A standard FieldFox RF VNA provides T/R measurements, or S11 and S21, with magnitude and phase. Adding Option 122 (full 2-port S-parameters) allows two-port cal and measurement of all 4 S-parameters at the same time.

Using FieldFox´s vector voltmeter (VVM), similar to the 8508A, the phase shift and electrical length of a device can be measured. The VVM option also provides ratio measurements of two channels, A/B or B/A.
FieldFox´s other application include distance-to-fault and VSWR testing, absolute power measurements, and characterization of 75-ohm cable TV devices.
