The base FieldFox RF VNA provides transmission/ reflection (T/R) measurements, or S11 and S21, with magnitude and phase. Adding Option 122 (full 2-port S-parameters) brings new levels of accuracy and convenience for testing RF components. A full 2-port network analyzer lets you measure the forward and reverse characteristics of your components without having to disconnect, turn around, and reconnect them to the analyzer. It also provides full 2-port calibration to give you the best measurement accuracy possible.
Use FieldFox to make return loss, VSWR, insertion loss/transmission, one-port cable loss, and distance to fault (DTF) measurements. You can test antennas, cables, filters, and amplifiers with a single handheld instrument. FieldFox can make return loss and distance-to-fault measurements at the same time. It helps you correlate overall system degradation with specific faults in the cable and antenna system.
FieldFox can connect with the Keysight U2000 Series USB power sensors to make RF/ microwave power measurements up to 24 GHz. Using FieldFoxs vector voltmeter (VVM), the phase shift and electrical length of a device can be measured.
