Hello all,
at the moment, we want to do some data acquisition using a
PCI-DA64/M1/16 card from Measurement Computing.
Unfortunately, there are no signal diagrams as example for
applications available. With the technical information we have at the
moment, all these things regarding pacer, trigger and gate are a
little bit confusing since these names are not used consistently but
sometimes simultaneously in that documents.
What we want to do is the follwing: After a trigger impulse, 1024
samples of data (analogue signals) should be collected via an analogue
input and transferred into a LABVIEW program for further processing.
Following the next trigger impulse, another 1024 samples should be
acquired, and so on.
Formerl
y, we were using another card which provided a clock output of
10 MHz. This signal was then reduced in frequency using one of the
card's counters as a frequency divider.
Unfortunately, the PCI-DAS64/M1/16 does not seem to have such a clock
output so we have to apply an external clock. That would be not a
severe problem since we could use a function generator for that
purpose. But what signals are required then? What shape is required
for the clock signal?
How should the card be wired? At the moment, it is impossible for us
to answer these questions. Therefore, we would greatly appreciate any
help.
Thank you very much in advance and best regards,
