Acquire
Specifies the acquisition mode of the Express VI. The following modes are available:
N Samples—Every time the VI is called, it returns a finite number of samples. This set of samples is not phase continuous with the previous acquisition.
Continuously—The first time the VI is called, it initiates a continuous acquisition on the digitizer. Subsequent calls fetch the next set of data, phase continuous with the previous set, from the digitizer. The maximum rate at which acquisition can be accomplished without error depends on the hardware/software configuration. Maximum rate is accomplished by tuning the Read length for most efficient transfer (typically 100,000 to 500,000 points).
