Description

The GX5292e is a high performance, cost-effective 3U PXI Express dynamic digital I/O boards offering 32 TTL or LVDS input or output channels with dynamic direction control. The GX5292e also supports 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 GX5292e supports 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 GX5292e supports 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 1.5 V, 1.8 V, 2.5 V or 3.3 V (5 V 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 16 MB, thus preserving test system resources. A direct mode, for continuous data transfer between the test system controller and the I/O pins of the GX5292e is also supported.

The GX5292e offers 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 GX5292e’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 2048 Mb per channel.

The GX5292e provides 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 input and output clock is also provided.

The GX5292e’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, address range or through a defined block of memory.  A Stimulus / Response digital test mode is supported and used for driving and capturing data.

Programming and Software

The GX5292e is supplied with DIOEasy, which provides powerful graphical vector development / waveform display tools as well as a virtual instrument panel, 32-bit DLL driver libraries, and documentation. The virtual panel can be used to interactively adjust and control the instrument from a window that displays the instrument’s current settings and status.

In addition, various interface files provide access to the library for programming tools and languages such as ATEasy, C/C++, Microsoft Visual Basic®, Delphi, and LabVIEW.

Optionally, DtifEasy is available for use with the GX5292e. DtifEasy offers a complete LASAR post-processor and test execution environment for post-processing and executing of LASAR generated .tap files.
