Vector network analyzer (VNA)

• 30 kHz to 9 GHz
• Directivity > 42 dB, dynamic range 100 dB to 9 GHz,
• Flat output power (± 1 dB) across whole frequency range, adjustable in 1 dB steps
• Transmission/reflection (S21, S11), or full two-port (S21, S11, S12, S22)

Cable and Antenna Analyzer (optional)

• 30 kHz to 9 GHz
• Distance-to-fault, return loss, cable loss

Vector Voltmeter (VVM), Power Sensor, and built-in measurements (option dependent)

• VVM: 30 kHz to 9 GHz, compare phase and electrical length
• Power measurements with USB sensor: 9 kHz to 24 GHz (sensor dependent)
• Built-in power meter: 100 kHz to 9 GHz

N9925A is a portable battery-operated microwave vector network analyzer, base is a transmission/reflection (S11, S21) VNA; configurations also include full 2-port (S11, 21, S12, S22), cable and antenna analyzer, power meter, vector voltmeter.

Delivers Keysight-quality Measurements — Wherever You Are
The N9925A FieldFox 9 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.
