Data Type: float64
Description: Specifies in Hertz the rate at which to clock the analog-to-digital converter. This clock is specific to the analog input section of multiplexed devices.

By default, NI-DAQmx selects the maximum convert rate supported by the device, plus up to 10 microseconds per channel settling time. Other task settings, such as high channel counts or setting Delay, can result in a faster default convert rate.

CompactDAQ applies up to 10 microseconds of settling time for all C Series devices even if the maximum convert rates of the devices differ.

If you connect signal conditioning accessories with track and hold capabilities, such as an SCXI module, to the device, NI-DAQmx uses the fastest convert rate possible that meets the settling requirements for the slowest module sampled. Refer to the device documentation for the signal conditioning accessory for more information.
