The SMX-4410 is a 3U, high-density PXIe matrix module that allows the user to connect any input row to any output column, with a DPST relay at every row/column cross point. This architecture provides the framework for flexible switch system designs where multiple test instruments need to be connected to common test points.
The SMX-4410 contains four (4X10) 2-wire matrix blocks that can be bussed together under software control to create 2 (8x10), or 1 (8x20), or 2 (4x20), or 1 (4x40) 2-wire matrix, providing the user flexibility and simplifying field wiring. The card is capable of switching up to 300V, 2A enabling it to be used over a wide range of applications. It also includes an embedded Self-Test mechanism that can be used to determine relay health.
The SMX-4410 incorporates extensive signal shielding and exposes shield pins on the front panel connector for tying to the cable shield. This preserves signal integrity throughout the signal path by maintaining the signals at the same reference level as the UUT. In addition, meticulous signal routing is done for signal shielding and cross talk reduction, allowing the SMX-4410 to achieve best in class switching performance. This performance allows the card to be used with high frequency signals, and signals that have fast rise times and narrow pulse widths.
