Does NI-6008 have both scan and channel clocks ?

Question

Does the NI-6008 have both scan and channel clocks whose rate can independently be set in LabVIEW ?  I would like to acquire say 100 samples on one channel at 10 kHz and repeat this at 10 Hz rate.  So 100 samples would be acquried at a 100 usec interval period (channel clock), then there would be a gap in time where no samples are acquired, then this process repeated again 100 msec (scan clock) later.

SteveP,
"Does the NI-6008 have both scan and channel clocks whose rate can independently be set in LabVIEW ?"
Yes and No.  You can set the sample rate (scan rate) on the
USB-6008/6009 but you cannot set the convert clock rate (channel clock)
on the USB-6008/6009.
Also, you cannot use an external clock with the USB-6008/6009 (in both the DAQmx driver and the DAQmx Base Driver).
The lack of both these feature limits you to one option to complete the task you want.
If you want to take 100 samples at 10kHZ every 100msec (10Hz) then you
will have to do a conintuous acqusition at 10kHz and use post
processing to drop the samples you do not need.
I hope this helps,
