125 MHz 1-16 Channel Digital Bit Stream PXI Card
The UX7005 has 64 Mbit/channel with 16 active channels, 128 Mbit with 8 channels, 256 Mbit with 4 channels, 512 Mbit with 2 channels and the entire 1024 Mbit when only using one channel.
For example, such a system would make it possible to record or generate a single 200 MSample per second analog signal with 8-bit resolution for up to 1 hour, or a 10 MSample/s signal for 20 hours.
Currently, the only other products offering this performance are based on high-end disk controllers costing at least $8000.
The document provides benchmarks of tests carried out using Strategic Test's UltraFast cards with a variety of PC motherboards and outlines some of the technical problems that can be encountered and possible solutions.
This information can also be useful to users of other manufacturer's.
Until now such information was not publicly available.
The application note can be downloaded from the company website.
