The three Read Status attributes/properties are useful for observing the progress of your acquisition.

  • The Current Read Position is the place in the buffer where the next read begins if the Relative To attribute/property is Current Read Position and the Offset is 0. In any case, the Current Read Position is always where the last read left it.
  • Total Samples per Channel Acquired is the total number of samples per channel acquired by the device and transferred into the buffer.
  • Available Samples per Channel is computed by first calculating the Current Read Position based on the settings of the Relative To and Offset attributes/properties and then subtracting this number from Total Samples per Channel Acquired.
