We would like to use simultaneous input output data acquisition using the
burst mode protocol.
The problem is that we notice that the operations are not simultaneous: first
a group and after the second.
We have try all tipe of pclk (internal and external) and we connect req1 and
req2 to an external manual trigger to have the same handshaking signal to
both the groups. We also try to differ the active high or low of both the
groups parameters.
In the vi attachment, you find the simple 2 groups acquisition chains and
it's easy to see that if you use an external clock of 1 Khz with 3000 input-
output samples, the total acquisition time would be 6 second instead of 3.
For our application it's necessary to use this protocol
(not the pattern
generation that we have tested in continuos and it worked) so we would like
to have a solution to this problem.
Since the pci DIO 32HS's manual asserts that it's possible to have 2
handshaking operation simultaneous we didn't aspect so many problems.
Thank you for your time
