I am trying do a sanity check before I order some hardware.
What I want to do is acquire from multiple channels in a SCXI chasis and as part of the same acquisition, also read from one of the "un-used" AI channels of the MIO card.
My concern is this:
All of the channels of the SCXI chassis get multiplexed down into a single channels of the MIO card that controls the SCXI chassis. This means that channel 0 has to do multiple A/D conversions to get a reading from all of the configured SCXI channels.
Meanwhile, the other AI channel of the MIO only has to do one to get it's reading. It seems that the on-board
clock of the MIO would have to run at two rates to be able to read all of my SCXI channels AND the other AI channel.
What I want to do:
I want to just configure a vitual channel for all of my SCXI channels AND one more for one "odd-ball" signal that is incompatable with all of the SCXI modules.
Then I just want to list all of my virtual channels when I configure and start my continuous double buffered acquisition.
I have successfully done all SCXI channels before, but I have never tried to use one of the un-used AI on the MIO at the same time. I have used the spare DIO lines previously, but that will not work in this app.
So...
If you have done this and it worked, I would greatly appreciate hearing about any special techniques that were used, etc.
Thank you for reading this question,
