Keysight (Agilent) 85106C Millimeter-Wave Network Analyzer Subsystem, 33 GHz to 110 GHz

The Keysight (Agilent) 85106C Millimeter-Wave Network Analyzer Subsystem is a rack-mounted extension platform for high-frequency S-parameter characterization operating from 33 GHz to 110 GHz. This subsystem expands the measurement capabilities of the 8510C network analyzer to millimeter-wave frequencies, enabling precise component and system characterization in research, development, and manufacturing environments. The system delivers real-time error-corrected measurements with 0.001 dB, 0.01 degrees, and 0.01 nanoseconds resolution.

TRL (through-reflect-line) calibration ensures accuracy across the measurement band.
