Keysight N9918B 26.5 GHz FieldFox Microwave Analyzer

Keysight N9918B is the next-generation FieldFox Microwave Analyzer with an optional 100 MHz real-time bandwidth and frequency coverage up to 26.5 GHz. To address the millimeter wave frequency requirements for 5G, satellite, and automotive radar industries, FieldFox can easily extend its frequency up to 110 GHz with an add-on downconverter.

FieldFox is also the industry’s most integrated handheld analyzer supporting over 20 key RF and microwave instrument functions, including a signal analyzer, full 2-port vector network analyzer, real-time spectrum analyzer, and over-the-air demodulation, CW signal source, power meter, and many more, in an all-in-one field proof package.

Keysight N9918B can withstand your toughest working conditions with a ruggedized yet lightweight and portable battery-powered design for measuring RF devices like cables, antennas, filters, amplifiers, and signal/spectrum analysis. Create your specialized handheld analyzer solution by selecting FieldFox options and features to address cable and antenna test (CAT) spectrum analysis (SA) or vector network analysis (VNA) real-time spectrum analyzer and over-the-air digital demodulation analysis required for your application.

The FieldFox analyzers are always ready to make RF measurements, ensuring every operating mode is flexible enough to meet the needs of novices and experts.
