The National Instruments PXI-2593 (Part Number: 778793-01) is a high-density 50 Ω RF Multiplexer Switch Module designed for flexible signal routing in PXI systems. This module supports configurations as an unterminated multiplexer, externally terminated multiplexer, or a dimensionally adaptable sparse matrix, effectively handling signal frequencies from DC up to 500 MHz. With 16 channels, the PXI-2593 features high-density push-on MCX connectors, enabling efficient and space-saving cabling solutions. It is optimized for integration with high-recurrence instruments, such as the NI PXI-5404 frequency generator and the NI PXI-5112 high-speed digitizer.

The PXI-2593 provides a characteristic impedance of 50 Ω, allowing for 10 W RF carry power and 150 V of CAT I switching between channels. The module is fully software configurable and boasts a typical relay operate time of 2.4 ms, a maximum relay operate time of 4.4 ms, and a mechanical relay life expectancy of 50 million cycles, with an electrical life expectancy of 300,000 cycles. Users can employ this module to form a versatile sparse matrix, facilitating signal routing between any channel pairs while ensuring high data transmission reliability and minimizing reflections.

Power requirements include 1 W at 3.3 V and 3.5 W at 5 V, with additional PXI Express requirements of 4.5 W at 12 V and 1 W at 3.3 V. The module is equipped with 18 MCX jack I/O connectors and two SMB jack trigger connectors. Compactly designed, the PXI-2593 measures 8.5 x 0.8 x 5.1 inches and weighs 12 ounces. Although this product has been declared obsolete by National Instruments, Apex Waves continues to buy, sell, and repair EOL NI hardware, providing ongoing availability.
