UsbDrDaqSetInterval

PICO_STATUS UsbDrDaqSetInterval(

short           handle,
unsigned long * us_for_block,
unsigned long   ideal_no_of_samples,
short         * channels,
short           no_of_channels

)

This function sets the sampling rate of the unit.

The fastest possible sampling interval is 1 microsecond, when the number of samples
is 8129 divided by the number of channels active and the 

 is BM

_SINGLE

. Under all other conditions, the fastest possible sampling interval is 10

microseconds.

handle:
