The Keysight U3042AM12 is a 12-port mechanical test set that extends 4-port network analyzers into full 16-port crossbar measurement systems. Operating from 300 kHz to 26.5 GHz, this unit enables complex multiport device characterization across RF and microwave frequencies. When paired with PNA, PNA-L, or PNA-X series analyzers configured with Option 551, the U3042AM12 delivers complete N-port calibration and measurement functionality for advanced engineering applications requiring multiport stimulus-response analysis.

– Compatibility & Integration
The U3042AM12 integrates with Keysight PNA, PNA-L, and PNA-X series 4-port network analyzers. Option 551 on the host analyzer is required to enable N-port calibration and measurement functionality. This configuration transforms a single 4-port instrument into a 16-port measurement platform capable of characterizing complex devices including arrays, manifolds, and integrated multiport components.
