pci counter specs?

[john fisher]

I'm a bit of a neophyte at this and am confused about what I require. I
have a 5V 500ns square pulse output from a SCA and want to buy a pci
counter board that will acurately count these pulses (assuming a 2000ns
pulse pair resolution). Does the oscillator frequency of the board have
any thing to do with the counting function? What specs for a board
should I be looking for? Thanks for any help.

It's an industrial board (with a corresponding price) but the one that I'm
using for my projects is called a pciDCC5-P board. Google should be able to
find it for you. It's a very capable counter/timer board with 5 16-bit
counters that can be cascaded in various ways under software control. There
was also an older ISA bus version of this board that's more-or-less software
compatable with it. If the 5 counters aren't sufficient, I believe there
are 10- and 15-counter versions of the board also.
