PXI bus mastering?

[weizbox]

I honostly dont know what PXI bus mastering is, but I belive I need to find out pretty soon. I have a project in which I will be needing to take in 16 million samples, 8 million on 2 channels from a PXI-5102 digitizer, and then analyze. The board itself i know can not handle this, but what it can do is "16 million samples to host RAM via PXI bus mastering " This is great, I need 16 million samples, now... how do I do this? Anyhting to get me in the right direction would eb greatly appreciated, thank you very much.

""I honostly dont know what PXI bus mastering is, but I belive I need to find out pretty soon."

I do not think you have to worry about what it is unless you plan on dropping this device in a non-NI chassis or do not plan on using NI-drivers.

PXI bus mastering

is a method interfaces can use to control the PXI bus in order to transfer dat from on-board buffers into system memory (or other devcies).

"Back in the Old days" (i.e. 30MHz CPU's) bus mastering was not available on all PCI busses. THen latter on it was available in some PCI slot on some computers but but not all (i.e. 400 Mhz CPU's).

I have never heard of an issues re: bus mastering in PXI chassis.

So...

Drop that board in a PXI chassis and load up NI-DAQ, configure it, and you should be
good to go. NI did all of the hardwork for you!

If want to be certain before purchasing the board just tell ask the sales person to have someone send you an e-mail indicating that the devices will do "X". I have done this anytime I was less than certain re: the fine print in a device spec.
