    Delivers Keysight-quality Measurements — Wherever You Are
    The N9928A FieldFox 26.5 GHz Vector Network Analyzer is equipped to handle routine maintenance, in-depth troubleshooting and anything in between. This versatile instrument's applications include: satellite communications, microwave backhaul, Military communications, radar systems, and active and passive device testing.

    Get Precise S-parameters
    The VNA's base function is a transmission/reflection analyzer (S11, S21), and it can be configured to include full 2-port S-parameters. FieldFox can be ordered with additional capabilities: cable and antenna analyzer, built-in power meter, vector voltmeter, variable DC source, and built-in GPS receiver — with results from trusted HP/Agilent benchtop vector network analyzers.

    Rugged Construction
    Dust-free design with no fans, no vents extends instrument reliability in harsh environments, water-resistant, MIL-PRF-28800F Class 2 compliant, and MIL-STD-810G, Method 511.5 Procedure I requirements for operation in explosive environments (type tested).
