Good Afternoon Erkki,
We have used the DSA-4472 products in conjunction with the PCI-PCMCIA expanders made by Magma successfully. In our application, we were making readings from a single channel on a DSA board. We do not have any benchmarks on transfer rates, but we were able to communicate and transfer data from the Data Acquisition Device.
Thanks,
Will Denman
