The National Instruments PXI-2593 is a high-density 50 ohm RF relay module. It can be programmatically configured as unterminated multiplexers, externally terminated multiplexers, or dimensionally flexible sparse matrices. Each configuration handles signal frequencies from DC to beyond 500 MHz. This 1-slot switch module uses high-density push-on MCX connectors for discrete yet manageable cabling. The NI PXI-2593 is designed to integrate with high-frequency instruments such as the NI PXI-5404 frequency generator and the NI PXI-5112 high-speed digitizer.
