The Keysight U3042AM08 is an 8-port mechanical switching extension test set that expands 4-port network analyzers to deliver 12-port full crossbar measurement capability. Operating to 26.5 GHz, this test set integrates with Keysight’s PNA, PNA-L, and PNA-X series analyzers to enable multiport characterization of complex RF and microwave devices. The unit connects via standard 3.5 mm RF connectors and operates under control of the host network analyzer through the rear panel Test Set I/O interface, requiring Option 551 on compatible instruments. System measurement range is limited by the analyzer’s frequency specification; units with upper frequency limits below 26.5 GHz will constrain overall performance accordingly.
