The Keysight U3042AE04 is a 4-port solid-state test set operating to 26.5 GHz, designed to extend PNA, PNA-L, or PNA-X network analyzers into full 8-port crossbar measurement systems. Built on solid-state RF switching technology, it eliminates mechanical switch limitations while delivering insertion loss under 0.4 dB and directivity greater than 22 dB at 40 GHz. The instrument handles up to 300 mW continuous power and accepts input signals to 10 dBm maximum safe level, with protection against 1 W transients. Housed in a compact 160 mm × 161 mm × 35 mm package with 50 Ohm 3.5 mm female connectors, the U3042AE04 supports precision multiport device characterization across 10 MHz to 26.5 GHz. Port isolation exceeds 25 dB at 40 GHz, ensuring signal integrity in demanding RF and microwave applications. Operating humidity to 80% relative humidity at 31°C, stepping down to 50% at 40°C, and requiring adequate ventilation or forced convection in cabinet installations, the test set maintains accuracy when thermal conditions stay within ±1°C of calibration ambient.
