Keysight N9915C 10 GHz FieldFox Handheld RF Analyzer

The Keysight N9915C 10 GHz FieldFox Handheld RF Analyzer is a portable instrument for testing radio-frequency and microwave systems. It brings several measurement capabilities into one rugged unit, helping engineers and technicians install, maintain, and troubleshoot equipment directly in the field.

Its cable and antenna testing capabilities help evaluate RF connections, antenna performance, and signal losses. With frequency coverage extending to 10 GHz, it supports measurements across a wide range of wireless and microwave applications. Additional functions depend on the configuration purchased.

Optional spectrum analysis displays signal strength across frequencies, helping users investigate interference and unwanted transmissions. Optional real-time spectrum analysis provides up to 120 MHz of gap-free bandwidth, making brief or intermittent signals easier to capture.

With vector network analyzer options, the N9915C measures signal reflection and transmission through RF components. It can measure all four S-parameters, helping characterize devices such as filters and cables and identify performance problems. Keysight lists a VNA dynamic range of up to 115 dB.

Further options support 5G NR and LTE over-the-air measurements and other specialized tests. Its software-defined design allows users to expand its capabilities as requirements change, making it a flexible tool for checking signal performance and diagnosing RF system faults.
