The Keysight U3042AM04 is a 4-port mechanical switching extension test set that expands network analyzer capability to 8-port full crossbar configurations. Operating to 26.5 GHz, it integrates with 4-port PNA, PNA-L, or PNA-X analyzers to enable complex RF and microwave measurements across multiple ports simultaneously. The unit delivers 5 million switch cycles and consumes 350 W maximum power. System performance is characterized when paired with compatible analyzers; frequency coverage depends on the host analyzer’s range. Single sweeps are recommended for multiport measurements to optimize switch life. Operating temperature range is 0 to 55 °C after 45-minute warm-up. The test set accepts mains supply voltage fluctuations to ±10% nominal. Environmental operation extends to 3,000 m altitude with humidity capability at 80% RH up to 31 °C, decreasing linearly to 50% RH at 40 °C. Requires adequate ventilation and dedicated AC line separation from motor-operated equipment. Safety Class I design includes protective earthing ground in power cord.

– Compatibility & Integration
Designed for integration with Keysight PNA, PNA-L, and PNA-X network analyzers. Frequency coverage extends to the full 26.5 GHz range only when paired with analyzers rated to ≥26.5 GHz. Use of N5221, N5231, or N5241 analyzers limits system range to 13.5 GHz maximum.
