The Keysight N9951A FieldFox is a handheld microwave analyzer that tests up to 44 GHz and can be used as an antenna analyzer, network analyzer, or spectrum analyzer. Keysight N9951A analyzers are lightweight, rugged, sophisticated test systems ideal for everything from routine maintenance to troubleshooting in harsh environments.

N9951A standard models are cable and antenna sweepers that can be upgraded to perform spectrum analysis, vector network analysis, and serve as power meters or vector voltmeters, thanks to Keysight’s customizable software options. Test engineers can measure TDR and DT in a single sweep, determine all four S-parameters at once, and perform precise spectrum analysis measurements without warming up. Calibration is simplified by Keysight’s QuickCal.

The N9951A weighs in at an incredibly light 3.2 kg, making it the most portable comprehensive analyzer in the industry. Keysight FieldFox analyzers harness the power of PowerSuite measurements, the same technology used in Keysight’s signal analyzers, giving users quick and accurate signal characterization.
