With the flexible architecture of the NI PXI-2576, you can configure it in a variety of topologies that make it suitable for parallel measurement operations requiring low-channel counts. In addition, you can combine all multiplexers on the PXI-2576 to form a single high-channel-count multiplexer featuring 64 2-wire channels. The module can be programmed with a variety of software including NI-SWITCH and NI Switch Executive. All National Instruments PXI switch modules are shipped with NI-SWITCH, an IVI-compliant driver offering complete functionality for all switch modules. For additional assistance in configuring, programming, and managing higher-channel-count switching systems, NI Switch Executive software offers an easy-to-use, intelligent switch management and visual routing environment. Use the NI-SWITCH Soft Front Panel for simple relay operations or debugging switch code/execution. Automatic Scanning The PXI-2576 maximizes throughput in automated test applications using scanning. Scanning improves throughput by downloading a list of up to 32,000 connections to the switch and cycling through the list using an event (trigger) without any interruption from the host processor. Scanning is most efficiently accomplished by mating the PXI-2576 with an instrument, such as the NI PXI-4070 6 1⁄2 -digit FlexDMM, which issues a trigger after each measurement. Relay Count Tracking The PXI-2576 counts relay closures on each relay. Relay counts are incremented each time a relay is actuated. You can retrieve the counts, stored on board the module, programmatically and use them for predictive maintenance to reduce unexpected system downtime.
