With 56 channels of TTL logic-compatible I/O, Marvin Test Solutions’ GX3756 Series digital-I/O instrument proves a versatile tool for military, aerospace, and industrial applications. The 56 channels come segmented into fourteen 4-channel groups in a high-performance 3U PXI hybrid slot-compatible instrument. Each I/O channel can be accessed utilizing read/write register commands and each group of four TTL outputs can be either enabled or tri-stated. The GX3756 comprises the GX3700 FPGA carrier card with Altera’s Stratix III FPGA and an I/O daughter card. The FPGA may be modified by customers to create customer-specific functions.
Four of the 56 TTL outputs can be configured to deliver 30-bit, 1-kHz serial data streams, while connector/cable identification is supported with three connector ID bits, further enhancing the utility of this card. TTL-input overvoltage protection ensures safe, reliable operation, and output state monitoring with the readback function provides the ability to verify programmed operation. A ruggedized, extended-temperature version is available for deployment of test systems in harsh environments.
The GX3756 Series is supplied with GxFPGA, a software package that includes a virtual instrument panel, and a Windows 32/64-bit DLL driver and documentation. Interface files are provided to support access to programming tools and languages such as ATEasy, LabVIEW, C/C++, Microsoft C#, and Visual Basic.Net. A Linux driver is also provided with the GtLinux software package.
