simultanous multirate-AI with cDAQ-9172 / LV

[zahnrad]

Hi, we are using the cDAQ 9172 device  with two 9233 and two 9215 modules. Is it possible to use these 4(2) modules with different AI rates at the same time - within one VI?
f.ex.: 2 x 9233  at  50k  and 1 x 9215 at 1k 

Following the 9172 User Guide there is only one Ai timing engine .... so there is no possibility to do so?

The 9215 runs at a max. rate of 100k - if i use it in cooperation with the 9233  module(max. rate 50k) - the max. "system" rate is then 50k??

Thank you!

Hello,

please have a look at this link:

There are different ways to determine the maximum sampling rate.
- DAQmx
- Web based cDAQ advisor
- Lookup tables

The maximum rate for your modules would be 50 kS/s
