Agilent/Keysight U3042AE04

The Agilent/Keysight U3042AE04 is a 4-port solid-state test set extension operating to 26.5 GHz. It integrates with PXI, PXI-L, and PXI-X 4-port network analyzers to enable complete 8-port full crossbar measurements for advanced RF and microwave characterization. Solid-state switching eliminates mechanical relays, delivering superior reliability and measurement repeatability across demanding test environments.

– Compatibility & Integration

The U3042AE04 connects to Keysight PNA, PNA-L, or PNA-X 4-port network analyzers, extending their measurement capability to eight ports. It operates within PXIe hybrid slots that accept PXIe and standard PXI modules. Chassis slot cooling capacity ranges from 38 W to 82 W per slot, with total backplane power typically around 858 W in 18-slot configurations. Configuration and measurement control flow directly from the host network analyzer.
