Buffered Data And Counter Reads

[joshua william powell]

Someone help me please....I need to do some fast digital data
acquisition with handshaking, which I think I can figure out. If anyone
has any hints on buffered data like that, please let me know. Also, I
need to read the status of three counters every time that handshaking
pulse comes in. I am not sure how to store the counter data in a buffer
(ie, hardware controlled)
I have to do it hardware controlled, because the DAQ rates have to
be fast....right around 1000 Hz or higher. Can someone offer any guidance
into how to do this? I believe I understand how to configure buffers for
the regular data recording and set up that handshaking, but I'm not sure
how to set up the counters so they write their values to a buffer (all

hardware controlled) when the handshaking pulse comes in.
If there are any books out there or anything, if someone could
tell me, I would be very appreciative. I always get the feelign grad
students are trying to do things that the hardware wasnt designed for. LOL

Thank you.

I am working on a project of high speed generation, and what I did was first to
look at the spec sheets of the 6533 (32HS) at www.NatInst.com That is a board
that buffers input and stores it till need be. The 6602 board has counters on
it that can be scanned when events happen. A small bit of math resulting from
those numbers can tell you a lot about when such triggering events happened.
Hope this helps,
