NI Releases New High-Density PXI Switch Modules for ATE System Engineers

NI Releases New High-Density PXI Switch Modules for ATE System Engineers
Five New PXI and SCXI Switches Expand Breadth, Density of NI Switch Offering

NEWS RELEASE -- Nov. 11, 2003 -- National Instruments extends its switch offering with the release of five new high-density PXI and SCXI flexible switch modules that deliver increases of 433 percent in relay density. The NI PXI-2530, SCXI-1130, PXI-2529, PXI-2567and SCXI-1167 switches address a wide range of applications to meet the design needs of automated test equipment (ATE) engineers.

The PXI-2530 and SCXI-1130 switch modules are high-density, 128-channel and 256-channel, multiconfiguration multiplexers/matrices. With 14 possible topologies and multiple expansion options, these modules offer an excellent solution for large or complex high-channel-count systems with a switching speed of 900 ch/s. These modules are the perfect front-end for high-speed measurement devices, such as the NI PXI-4070 6 ½-digit FlexDMM, in applications such as ECU or IC testing.

The PXI-2529 high-density multiconfiguration matrix brings a 128 crosspoint, two-wire matrix to a single-slot 3U PXI module, increasing PXI matrix density by 433 percent. Able to switch up to 150 VDC or 150 Vrms CAT I and up to 1 A switching/2 A carry, this module is designed for systems that require the flexibility of routing multiple test points to several instruments in a matrix configuration. With this new module, engineers now can create an expandable test platform involving several modular instruments in the same PXI chassis.

Finally, the PXI-2567 and SCXI-1167 64-channel, multipurpose relay drive modules accommodate up to 50 V or 600 mA of drive capacity. These modules can drive many types of external relays, including high-current, high-voltage or multipole RF switches. Like other NI switches, relay drive modules make use of NI-SWITCH driver software, so engineers can program external relays connected to the relay driver and standard PXI and SCXI switch products identically.

All NI switch hardware works with NI LabVIEW graphical development environment and NI Switch Executive switch management software. Additionally, the new switch modules track and store relay cycle counts that engineers can use to perform predictive maintenance on the switch module. To maximize system throughput, these modules also support hardware-triggered scanning. This makes the test sequences highly deterministic, ensuring tight synchronization between measurement devices and the switches.
