Geotest offers a user-configurable FPGA 3U PXI card that features 160 digital I/O signals for specific application needs. The GX3500 employs the Altera Cyclone III FPGA that supports clock rates up to 150 MHz and features over 55,000 logic elements. According to the company, the GX3500 supports expansion card assemblies (daughter cards) that can be used to customize the interface to the UUT, eliminating the requirement for bulky add-on boards that normally reside outside of the module. The company also asserts it does not require proprietary design tools. Also included in the GX3500’s software bundle is a virtual panel that helps facilitate interactive design, debug, and deployment of the module.
