Actual Sample Period (sec) Actual Sample Period is the actual interval between
samples in seconds, which is the inverse of the actual sample rate in hertz. The actual
sample period can differ from the requested sample rate, depending on the clocking
capabilities of your selected device.
error out Error out contains error information. If the error in cluster indicated an error,
the error out cluster contains the same information. Otherwise, error out describes the
error status of this VI.
ADAC AI Cont Scan
The ADAC AI Continuous Scan VI continuously collects the specified number of
samples at the specified sample rate and returns the waveform data.
If the error in cluster contains an error from a previous VI call this VI does nothing and
returns the error in cluster unmodified in the error out in a two dimensional array. This VI
typically acquires voltage readings on a single channel only, but may be used to collect
multiple channels into its 1 dimensional array.
Board ID (0) Specifies the ADAC-LVi board ID number to be used in this acquisition. The ID
numbers are defined in the configuration file ADAC-LVi.con located in the Windows main
directory.
