Keysight Technologies FieldFox handheld analyser options

Keysight Technologies has introduced two cable test options for its FieldFox handheld analysers: time domain reflectometry and extended range transmission analysis.

The time domain reflectometry (TDR) cable measurement option enables TDR measurements for the cable and antenna analyser. With this option, the FieldFox analyser becomes a suitable tool for any cable system test. The option complements the analyser’s return loss (RL) and distance-to-fault (DTF) measurements. Furthermore, it measures impedance changes along the cable and helps identify specific faults, while the analyser’s RL measurement capability exposes mismatch of cable connections and DTF capability indicates faults and poor connections along the cable.

The extended range transmission analysis option addresses one of the major challenges of measuring cables in the field: measuring in-situ, long lossy microwave cables. With extended range transmission analysis, two FieldFox instruments are deployed at each end of the measured cable. One analyser acts as a source, while the other acts as a receiver. Both instruments are step synchronised with hardware triggers. By taking advantage of Keysight’s InstAlign spectrum analysis technique, engineers and technicians can use this configuration to make accurate cable loss measurements without calibration and warm up. The option can also be configured with frequency offset to measure devices such as mixers and converters.
