    FieldFox 30-second video introducing real time spectrum analysis (RTSA)

    Designed to Withstand Your Toughest Working Conditions
    The N9914A FieldFox 6.5 GHz RF Combination Analyzer's base function is a cable and antenna analyzer and it can be configured to include a spectrum and network analyzer. FieldFox can be ordered with additional capabilities: power meter, independent signal generator, vector voltmeter, interference analyzer, variable DC source, and built-in GPS receiver.

    Noise Figure Analyzer Mode (Opt. 356)
    Expanding measurement capabilities include noise figure analyzer mode — a key performance parameter in many RF systems. FieldFox can characterize the noise figure of devices including low noise amplifiers (LNAs), frequency converters and receivers using the industry proven Y-factor technique. By combining noise figure measurements with full 2-port vector network analysis, spectrum analysis and power sensor integration, FieldFox can now provide complete characterization of amplifiers and converters in the field or repair depots.

    Independent source, vector voltmeter (VVM), power sensor and built-in measurements

    • RF source: 30 kHz to 6.5 GHz, CW, CW coupled, and tracking
    • VVM: 30 kHz to 6.5 GHz, compare phase and electrical length
    • Power measurements with USB sensor: 9 kHz to 24 GHz (sensor dependent)
    • Built-in power meter: 5 kHz to 6.5 GHz
    • Three-year warranty
