Agilent/Keysight P9164A

The Keysight P9164A is a 2×16 USB solid-state switch matrix that enables multiport vector network analyzer (VNA) solutions for complex RF test environments. This full crossbar switching device streamlines VNA calibration and measurement workflows, including 5G massive MIMO antenna characterization. Operating from 300 kHz to 6.5 GHz, the P9164A delivers exceptional isolation performance—87 dB at 300 kHz to 2 GHz and 85 dB from 2 to 6.5 GHz—minimizing crosstalk in dense automated test systems. The module features CMOS-based SPDT and SP4T switches with 50 µs switching speed and ultra-long cycle life, reducing overall cost of test. Internally terminated output ports maintain 50 ohm impedance when not in use, ensuring signal integrity.
