Agilent/Keysight 8410A

The Agilent/Keysight 8410A is a network analyzer mainframe that measures phase and amplitude characteristics of RF and microwave networks. Operating as a phasometer and ratiometer, it delivers direct, continuous, simultaneous phase and amplitude ratio measurements of RF voltages across a broad frequency spectrum. The system combines the 8410A mainframe with an 8411A frequency converter and 8412A phase/magnitude display to enable S-parameter characterization from 110 MHz to 12.4 GHz.

Compatibility & Integration The 8410A integrates with HP S-parameter test sets including the 8514B (45 MHz to 20 GHz), 8515A (45 MHz to 26.5 GHz), and 8516A (45 MHz to 40 GHz). The 8411A harmonic frequency converter and 8412A phase/magnitude display are standard system components. This is a discontinued product; manuals are available but Keysight provides limited current support.
