1 / 4 page NI PXI-2593, NI PXIe-2593, NI SCXI-1193 NEW! High-Frequency Multiplexer/Matrix Modules Overview and Applications NI PXI-2593, PXIe-2593, and SCXI-1193 are high-density 50 RF relay modules. You can programmatically configure them as unterminated multiplexers, externally terminated multiplexers, or dimensionally flexible sparse matrices. Each configuration handles signal frequencies from DC to beyond 500 MHz. These single-slot switch modules use high-density push-on MCX connectors for discrete yet manageable cabling. NI 2593 modules are designed to integrate with high-frequency instruments such as the NI PXI-5404 frequency generator and the NI PXI-5112 high-speed digitizer. Multiplexer Configurations The NI 2593 and SCXI-1193 are 16- and 32-channel unterminated multiplexers, respectively. With external 50 MCX terminators (P/N: 761930-01) on half of the channels, you can use these modules as terminated multiplexers. Table 1 shows multiplexer configurations for each module.

This table shows available multiplexer configurations. Dimensionally Flexible Sparse Matrix Configurations You can configure the NI 2593 modules as flexible sparse matrices, which you can use to route signals between any pair of channels or commons while maintaining >500 MHz bandwidth and minimizing reflections. Unlike a traditional sparse matrix made from two multiplexers with their COM terminals connected, these modules use a flexible architecture in which you can define the row and column dimensions. There is no restriction on row-to-row or column-to-column connections. For example, you can configure the 18 terminals on the NI 2593 modules as a 2x16, 4x14, or 9x9 sparse matrix, or any size in between. It is even possible to connect multiple crosspoints simultaneously. Figure 1 demonstrates the configuration capabilities of an NI 2593 as a dimensionally flexible sparse matrix. 500 MHz bandwidth ■ 50 characteristic impedance ■ 10 W RF carry power ■ 150 V, CAT I switching ■ Fully software configurable ■ Unterminated multiplexer ■ Available in both PXI and PXI Express ■ versions for optimal slot placement Configurations NI SCXI-1193: 32x1, dual 16x1, ■ quad 8x1, nine 3x1 NI PXI-2593/ NI PXIe-2593 (NI 2593): ■ 16x1, dual 8x1, quad 3x1 Terminated multiplexer configurations ■ NI SCXI-1193: 16x1, dual 8x1, ■ quad 4x1 NI 2593: 8x1, dual 4x1 ■ Sparse matrix configurations ■ NI SCXI-1193: 36-terminal ■ NI 2593: 18-terminal ■ Operating Systems Windows XP/2000/Me/9x/NT ■ Recommended Software LabVIEW ■ LabWindows ■ ™ /CVI Measurement Studio ■ for Visual C++ NI Switch Executive ■ Other Compatible Software Visual Basic ■ ANSI C/C++ ■ Driver/Software (included) NI-SWITCH ■ |
