Genereal Switch Questions

[Havarti]

What is the difference between the Matrix, Multiplexer and General Porpuse modules? 

Why are some SCXI and some PXI is there and advantage to one over the other?

Why do I see some modules under multiple types here: http://volt.ni.com/niwc/products/switch_topologies.jsp? 

Whats the difference between 145 Cycles/s, 25,000 Channels/s, 2000 Crosspoints/s, 10 ms, which are all listed under switch speed on the same page?

Thanks for the help,

Brian

We have quite a few documents that answer your questions:

Understanding Switch toplogy

Why are some SCXI and some PXI is there and advantage to one over the other?

Choosing a Switch Platform: PXI or SCXI 

Why do I see some modules under multiple types here: http://volt.ni.com/niwc/products/switch_topologies.jsp?

Some modules can be configured as multiplexer or matrix by using a very flexible design and placing judiciously relays on the PCB.  

Whats the difference between 145 Cycles/s, 25,000 Channels/s, 2000 Crosspoints/s, 10 ms, which are all listed under switch speed on the same page?

The difference comes from the type of switch modules you are referring to. Cycles/s, Channels/s, Crosspoints/s are for genral purpose, multiplexer, and matrix respectivelly that can be used in scanning mode.

ms indicates speed on switch mdodules that do ot suipport scanning.

I encourage you to look over this document: Complete Switching Tutorial. You can also find several technical documents on this page: Switch Application Notes
