Introduction
The GX5280 Series are high performance, cost-effective 3U PXI dynamic digital I/O boards with 32 TTL I/O
channels and 32 LVDS I/O channels. The GX5280 Series offers an industry leading 512MB of on-board memory
and allows test rates up to 200 MHz (GX5283 Only). The single board design supports both master and slave
functionality without the use of add-on modules. Channels direction can be programmed on a per byte basis, i.e.
Group 0 (channels 0 -7) can be set as output while Group 1 (channels 8 -15) can be set to be input etc. Output
channels data is present on both LVDS and TTL Standard level I/O connectors. If the specified group is in input
mode, the user can select (software) which input interface to activate, i.e. LVDS or level (one of 3.3. 1.8, 1.5, 2.5).
The GX5280 Series utilize the PXI Local Bus to distribute signals across a domain.
All GX5280 cards offer programmable I/O width - trading vector width for vector depth. The GX5283 vector
memory can be configured to support channel widths of 32, 16, 8, 4, 2 and 1 (single channel) with corresponding
vector depths of 128M steps, 256M steps, 512M steps, 1G steps, 2G steps and 4G steps. The GX5282 vector
memory can be configured to support channel widths of 32, 16, 8, 4, 2 and 1 (single channel) with corresponding
vector depths of 64M steps 128M steps, 256M steps, 512M steps, 1G steps and 2G steps. The GX5281 vector
memory can be configured to support channel widths of 32, 16, 8, 4, 2 and 1 (single channel) with corresponding
vector depths of 32M steps 64M steps, 128M steps, 256M steps, 512M steps and 1G steps.
Marvin Test Solutions’ DIO is a family of high-speed, programmable, dynamic Digital Input and Output (I/O)
boards. These boards perform high-speed automated functional testing, device testing, simulation and data
acquisition. The DIO family provides real-time digital pattern capture and generation with 32 channels per card and
up to 16 cards or 512 channels.
The DIO family uses common software development tools to develop test vector files. The test vector files contain
digital patterns sent to or received from the Unit Under Test (UUT) and specific pre-defined setting for each board
in the setting.
Using DIOEasy or DIO driver functions, the development of vector files can be done without using the actual
hardware . Vector file verification requires the DIO be installed and properly configured.
Marvin Test Solutions bundles DIOEasy with all DIO products. DIOEasy , Marvin Test Solutions’ vector
development and analysis software, allows manual control of the DIO hardware using the built-in DIO Virtual
Instrument Panel. The DIO driver permits control of the DIO family from common software development tools such
as Marvin Test Solutions’
ATEasy , Microsoft Visual Basic, Microsoft Visual C++, Borland C++, Borland Delphi
and more.
DIOEasy , a Windows application used to develop digital vectors and does not require any programming experience
or knowledge to operate.
Computer Bus Interface
The DIO Driver accesses Master, Slave and carrier boards through the computer’s bus (see Figure 2-1). The driver
can accommodate up to 16 masters (from either family) and each master can have up to 7 DIO slave boards. ISA
based DIOs and carrier boards have switches to set their base address to identify by the driver where PCI and PXI
boards are using the physical slot number they are installed in to identify by the driver. PXI and PCI boards Master
and Slave numbers are set through selector switches located on the front.
