The sampling rate of 5102

The max sampling rate of 20M is for one channel or 2 channels?
Will the rate be half, 10M, if I use 2 channels?
 
If I use 2 cards, will it affect?

Hey Turbot,

Thanks for contacting National Instruments support.  The specifications say that this sampling rate is for both channels simultaneously.  Using two cards will not affect the rate of the ADCs on the boards.  Let me know if you have further questions.

According to specs, its memory size is around 660,000, is it for 2 channels totally, or for each channel? Thx.

Hey Turbot,

That is total memory size.  Unless it says "per channel", or "each channel" it's total memory.  Let me know if you have further questions.

Hey Turbot,

I stand corrected.  I will put in an error in the documentation, it should say per channel, or each channel.  A look at this devzone at the bottom shows the true answer, that there is 663,000 samples per channel.

Sorry for the confusion.
