Description
The GX5290 Series are a high performance, cost-effective 3U PXI dynamic digital I/O boards offering 32 TTL or LVDS input or output channels with dynamic direction control. The GX5290 Series also support deep pattern memory by offering 256 MB of on-board vector memory with dynamic per pin direction control and with test rates up to 100 MHz. The single board design supports both master and slave functionality without the use of add-on modules.
Features
The GX5290 Series support selectable I/O levels of 1.5 V, 1.8 V, 2.5 V, or 3.3 V (TTL, LVTTL, CMOS, LVCMOS). In addition, the GX5290 Series support 32 differential channels for LVDS, M-LVDS, or LVDM logic families. The TTL/LVTTL interface utilizes a programmable voltage source, which sets the output logic levels from 1.4 V to 3.6 V. Programmable thresholds of 1.5V, 1.8V, 2.5V or 3.3V (5V compatible) are supported for input signals. Recommended operating input voltage range is from 0 V to 5.5 V.
A windowing method is utilized for PCI memory accesses, which limits the required PCI memory space for each board to only 16MB, thus preserving test system resources. A direct mode, for continuous data transfer between the test system controller and the I/O pins of the GX5290 Series are also supported.
The GX5290 Series offer 256 MB of vector memory, with 64 Mb per channel. Programmable I/O width allows trading vector width for vector depth. Under software control, the GX5290 Series's vector memory can be configured to support channel widths of 32, 16, 8, 4, 2 and 1 with corresponding vector depths of 64 Mb, 128 Mb, 256 Mb, 512 Mb, 1024 Mb, and 2048Mb.
The GX5290 Series provide programmable TTL/LVTTL output clocks and strobes, and supports external clock and strobe. A programmable PLL (phase locked loop) provides configurable clock frequencies and delays. An LVDS output clock is also provided.
The GX5290 Series's sequencer can halt or pause on a defined address or loop through the entire memory as well as loop on a defined address range or through a defined block of memory.
Programming and Software
The board is supplied with GTDIO/DIOEasy, a software package that includes vector editing, a virtual instrument panel, and 32/64-bit DLL driver libraries and documentation. The virtual panel can be used to interactively program and control the instrument from a window that displays the instrument’s current settings and status. In addition, interface files are provided to support access to programming tools and languages such as ATEasy, LabView, Microsoft® and Borland® C/C++, Microsoft Visual Basic®, Borland Delphi, and Pascal. On-Line help file and PDF User's Guide provides documentation that includes instructions for installing, using and programming the board.
