Research (Phase 1),
need a AtoD solution, that
interfaces DMA to a typical computer (PCI/PCI-X/PCIe) 64bit mobo.
(could be intel/amd processor).
Must mount compact (i.e. riser L card?), or via cable?
Must work with Linux OS, and programmable fully by C.
Most important, must be able to capture analog and convert to
digital (10,12,16 bit?), at 25Ms/s or higher (even to 100Ms/s.
Solution may be custom build?
Solution should not be expensive, i.e. if a off-the-self exists for
1000.00$ that would be the solution (for this phase), if
its $5000.00, then one needs to seriously look at custom build.
In a future phase, a custom build will happen, to mass produce this
and at a cheap cost. i.e. 100-400$ US for a pci-? card, suited to a refined task.
At this stage in the project, (Phase 1), all is required is research.
What products out there, if any, can do this, and for how much?
If expensive, is the next phase a custom build.
Other issues like differential sampling (verses reference), and
protection of the electronics to damage also have to be considered.
Also, a combination of slower A2D's is not acceptable, it must be a single input able to sample 25Ms/s+.
This spec. can be expanded upon if need be (bidder has more questions)
Future phases will include software development, and custom build
(based on findings of this phase).
Extra consideration may be given to bidders who have abilities to take on future phases.
Will probably except multiple bidders, to have benfit of two or more
people working on it, so nothing is missed.
I can except a single bid on this one, and issue another project to another bidder.
Money will be placed in escrow.
Except delivery in 2-3 parts, and release of escrow same.
i.e. (1) initial possibilities
(2) short list
(3) results including contact with vendors and/or data sheets etc.
project budget can lead to more if tasks become more involved.
The following is the best I have found:
8-bit A/D PCI Express x1 board. 50 MS/s $3,499.00
supported by Linux and C programming
So I am looking for something as capable, but cheaper.
If you have a very good idea to build one, and it would be inexpensive, then that is of interest too.
I will also post another brother project of this, to do with a strobe, that might be of interest.
Sorry, had to extend, just in middle of buying home, and cannot get time to finalize this, hopefully this weekend or shortly there after.

Hi , I'm an engineer who worked a lot with data aquisition hard and soft .I had various projects involving DAQ from scratch to sofware development. I think your project can be done with existing hardware ...
