Agilent/Keysight 8410B

The Agilent/Keysight 8410B is a precision network analyzer engineered for characterization of high-frequency electrical networks across RF and microwave applications. It delivers S-parameter measurement, impedance analysis, phase tracking, and frequency response data essential for design validation of filters, amplifiers, and antennas.

Technical Specifications

Frequency Range: 10 MHz to 20 GHz Measurement Parameters: S-parameters, gain/loss, impedance, phase angles (0 to 360°), magnitude ratios (dB), frequency response, and time-domain measurements Dynamic Range: 60 dB (phase and magnitude ratio), 100 dB (alternative specification) Measurement Speed: Up to 150 points per second Resolution Bandwidth: 1 Hz to 3 MHz Measurement Channels: 2 Power Levels:

• Reference Channel: −16 dBm to −44 dBm


• Test Channel: −10 dBm to system noise floor (typically −78 dBm or lower)


• Test Channel maximum: 20 dB above Reference Channel Power Supply: 100–240 VAC, 48–440 Hz Weight: 13.6 kg

Key Features

• Integrated automatic calibration and error correction for measurement consistency


• Dual-channel architecture for simultaneous RF voltage phase and magnitude ratio measurement


• Complex S-parameter network characterization in small-signal mode


• Harmonic frequency converter compatibility (Model 8411A) for extended measurement capability via RF mixer and step recovery diode harmonic generation

Typical Applications Device characterization including passive and active RF/microwave networks, component qualification, and circuit validation across the 10 MHz to 20 GHz band.

Compatibility & Integration Interfaces include GPIB, RS-232, and LAN for control and automation. The 8410B integrates with compatible sweep oscillators (HP 8620C) for continuous multi-octave frequency sweeps. Operates as part of a modular system with display units and optional frequency conversion modules.
