The Keysight U3042AE12 is a 26.5 GHz, 12-port solid-state test set that extends the measurement capability of PNA, PNA-L, and PNA-X network analyzers to enable 16-port full crossbar characterization. The instrument uses solid-state RF switching and coupler-based architecture to deliver low insertion loss measurements with 0.1 dB uncertainty and high repeatability across its 10 MHz to 26.5 GHz operating range. Direct control via the connected network analyzer eliminates external PC or software requirements, while support for full 16-port calibration (with Option 551) allows complete measurement of all 256 S-parameters in multiport device and system testing.

– Compatibility & Integration
Connects directly to Keysight PNA, PNA-L, and PNA-X network analyzers via rear panel test set I/O. Network analyzer options required vary by model: Option 401/417/419 (N5222A/B), Option 245/145/246/146 (N5230A/C), Option 416 (N5232A), or Option 400 (N5242A). Option 551 enables full N-port calibration. Specific `.tsx` test set files required for multiport operation installation.
