Agilent/Keysight U3045AM04

The Agilent/Keysight U3045AM04 is a 50 GHz, 4-port mechanical test set that extends compatible 4-port network analyzers to enable 8-port full crossbar measurements. It augments PNA and PNA-X systems, delivering the multiport characterization capability required for complex device testing. The test set supports N-Port calibration—essential for accurate multiport S-parameter extraction and device validation across the full 50 GHz frequency range.

– Compatibility & Integration

The U3045AM04 integrates with Keysight PNA and PNA-X series 4-port network analyzers. Option 551 is required on the host network analyzer to enable N-port calibration and full multiport operation. The network analyzer’s frequency range must meet or exceed 50 GHz for complete system coverage. Environmental specifications follow those of the host PNA series system. The test set complies with applicable safety and regulatory requirements for its intended installation location.
