The Keysight N2272A RF high-density module provides a 1x9 multiplexer which can be widely used in RF test and measurement systems. It consists of a series of eight RF latching relays in a tree structure. The module's low insertion loss, high isolation, and excellent VSWR performance guarantee the RF signals will not be degraded when routed from source to destination. In order to decrease the degradation when cascading, the auxiliary channel (channel 08) with smaller insertion loss and lower VSWR, is provided to extend the channel count. This is done by connecting it to the COM channel of the next N2272A module. It can also be used as a standard channel. The BNC connectors on the module front panel are provided for ease of wiring. The N2272A can only be operated in SCPI mode when installed in 3499A/B mainframes with firmware 3.0 or later.

See the new 34980A Multifunction Switch/Measure Unit as a new low-cost alternative.
