NI 9220 sampling mode

[linu95k]

I am trying to understand if NI 9220 is simultaneous sampling module, since we are receiving conflicting information from multiple sources, can we verify this and provide a confirmation?

As per my understanding it has a SAR (Successive Approximation Register) which is used for simultaneous sampling. However no-where in the specification sheet does it mention the simultaneous sampling mode.

1. In Description of the module it states 100KS/s/ch
   
2. However, on the datasheet it mentions 100kS max sampling
   

   Can someone please confirm this?

I see the word "simultaneous" twice in your image…

The spec does NOT mention a shared sample clock for all channels.

Instead of specifies a generic "upto 100kS/s" regardless of the channel count - as is typical for simultaneous sampling…
