Digital I/O card is flexible about its
16 channels
PCI Express based digital bit stream card has 16 channels that can all be set to either input or output with a maximum clock rate of 125MHz.
New from Strategic Test, the PCI Express based UF2e-7005 digital bit stream card has 16 channels that can all be set to either input or output with a maximum clock rate of 125MHz What makes this card unusual is that it is possible to use only one, two, four, eight or 16 channels with access to all the available card memory

Ultra-fast sampling board runs up to 125Mbit/s
The UF.7021 is a full-length PCI board with 64 digital input or output channels that can simultaneously capture and replay signals at a maximum sample rate of 125Mbit/s.
Also, when using fewer channels, it is possible to stream the data to or from a PC at higher rates than usual, allowing much longer signals to be recorded or generated.
"While a number of high-speed digital input and output boards are available, these typically provide 16 or 32 fixed channels and as a consequence map the entire available card memory to these channels", says Bob Giblett, President of Strategic Test.
"For applications that require recording or playback on fewer channels, this effectively wastes expensive card memory or requires more memory to be purchased in order to achieve a specific recording or playback duration".
The UF2e-7005 is equipped with 64Mbyte memory as standard, but can be expanded to 4Gbyte.
This enables signals to be recorded or generated for periods of up to 16s on 16 channels at 125MHz and to 262s when using just one channel.
For many applications, it will not be necessary to purchase additional memory as the signal data can be streamed to or from the host PC.
As the PCI Express x1 bus has a maximum continuous transfer rate of 120Mbyte/s this means 8bit or less can be streamed at just less than the maximum clock rate, and one, two or four channels can be streamed at the maximum rate.
Thanks to the serial bus nature of PCIe, every card can operate at this rate, unlike the 66/33MHz PCI bus where the bandwidth is shared between multiple cards or attached motherboard devices.
Strategic Test provides comprehensive software support, with software development kits available for: Windows Vista and XP64, XP, 2000, NT and 98; Linux drivers for RedHat, Suse, Fedora and Debian; Matlab; LabView; Agilent-VEE; LabWindows/CVI; and DasyLab.
Prices for the UF2e-7005 start at US $3790.
This includes a signal cable, MS Windows and Linux SDKs, program source code examples, two year warranty and lifetime support and SDK updates.
