Keysight's FieldFox handheld analyzers are equipped to handle your toughest working environments during routine maintenance, in-depth troubleshooting, and anything in between. Choose the software-enabled FieldFox configuration that best meets your needs.
Given the new dynamics of wideband, microwave and millimeter wave communications, Keysight developed the next generation FieldFox Microwave Analyzer with 120 MHz of real-time bandwidth and frequency coverage up to 50 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 industries most integrated handheld analyzer supporting over 20 key RF and microwave instrument functions including signal analyzer, full 2-port vector network analyzer, real-time spectrum analyzer, over-the-air demodulation, CW signal source, power meter and many more, in an all-in-one field proof package.

Notes:
¹ Models N9913/33B, N9914/34B and N9915/35B do not support frequency extenders. This is because the mixers’ starting LO frequency is higher than 9 GHz and the FieldFox Port 1 provides the LO to the mixer.
² Useable to 5 kHz.

NOTES:
1. Useable to 5 kHz for N993x/6xB.
2. Order Option 100 for 3.5 mm (m) test port connectors. With N9938B-100, the spectrum analyzer is built with 3.5 mm test port connectors instead of the standard Type-N (f). Option 100 is a prerequisite for Option 320 for N9938B.
