Simultaneous Analog Input and Analog Output at different rates Using USB 4431

[Anil_Reddy]

Hi,

I am trying to do simultaneous analog output and analog input at different rates using USB 4431. 

When i set the sample clock for 2 tasks differently, i get error  "-200660" when i start the second task. I tried to use on-deman sample type. But this board does not support.

am trying all the options. going clue less.

appreciate help from the forum........

Thanks in advance

Anil

Hi Adnan,

It worked...there was no manual for this card. they just gave specifications. and it is pretty new card (released in march). 

Now i should restrict the input sampling rates to some fixed numbers (This card has some fixed analog output update rates).

Thanks

Hello All,

The available sampling rates for Analog Input on the USB 4431 are on page 1 of the NI USB-443x Specifications.  The available update rates for Analog Output tasks are on page 3 of the same document.
