Remarks

 

With the exception of some products, the sampling clock can be set in 0.025usec (25nsec) increments.

The conversion speed that can be set depends on the number of channels used.

Even if a configurable conversion speed is set, the conversion may stop due to an error because the processing by the driver is not in time.
The USB device is completely dependent on your environment, so if a sampling clock error occurs, please lower the clock.
