Simultaneous buffered and one-point data acquisition from a single channel with a USB-6009?

[GeoffHammond]

I want to sample the same signal as a buffered read (at 4 KHz) and point-by-point (at 200 Hz). Can I do this simultaneously from a single channel or do I need to copy the signal to separate channels?

Thanks for your replies,

Geoff Hammond

The device has a single A/D convert clock and you cannot have different sample rates for different channels. Why would you even need another acquisition of the same channel? You can manipulate/reduce the data from the 4 kHz acquisition and pass it to another part of your progam (i.e. with a queue)
