How do I deal with a cascaded system, First Stage SCXI-1520's and Second Stage SCXI-1143's?

I am aware of the following link:

I'm kind of stuck here.  The system is already in place.  1520's in first stage and 1143's in second.  I am supposed to configure the 1520's and scan the 1143's.

What problems do you see with this?

How do I go about doing an end to end calibration?

Should I just rip out the 1143's and hope nobody notices?

Hello Frank,

Let's start from the beginning.  I understand that you have some SCXI-1520s and 1143s that you are using in your measurement system. What type of sensors are you acquiring data from? It seems that you intend to use the 1143s to filter the data between the 1520s and the software.  Is this correct? Another question that I have is what do you mean by "end to end calibration?" The more specific that you are about the application you are developing, the easier it will be for others to help you with any questions that you might have.

Looking at the knowledge base article that you linked in your original post, it seems that the point was to filter the data from the SCXI-1520 in software, using the LabVIEW Filter Express VI. Would this be a viable option for you? If so, then you could just rip out the 1143s.
