Separate sampling rate for two different channels for a USB-6009 daq

[Zeebra]

Hi, 

I am using a USB-6009 and incorporating the 'daq assistant' to change the sample rate.  I am trying to find a way to set the sampling rate to two unique values for two separate channels.  I've tried setting up two daq assistants and adjusting the sample rate different for each channel, though this does not work.  Is there any way to set the sample rate high for all channels then reduce the rate for a different channel - or an alternative?  I would appreciate any input on this, thank you!

All tasks on a DAQ board that use a sampling clock must use the same clock.  Therefore, you cannot have two tasks on the same DAQ board sample at different rates.

Alternatives would be:

1. to combine all of the channels into a single task and just accept the extra data

2. get an extra DAQ board to use in parallel
