Delivers Benchtop Accuracy and MIL-Spec Durability to
Field Applications
Keysight Technologies, Inc. FieldFox brings bench-level accuracy into the eld by delivering
precise handheld RF and microwave measurements that agree with benchtop analyzers.
FieldFox RF and microwave analyzers include: spectrum analyzers (N993x), full 2-port vector
network analyzers (N992x), and all-in-one combination analyzers (N991x). The combination
analyzer’s base function is a cable and antenna analyzer and can be congured to include
spectrum and network analysis.
