Distributed run-time auto-calculation of measurement uncertainty

Abstract:

System and method for auto-calculating uncertainty of a measurement performed by a measurement device. The measurement device initiates a measurement or measurements. In response to the measurement initiation, a driver of the measurement device sends an error specification request to each of a plurality of hardware modules involved in the measurement. Each of the plurality of hardware modules determines the requested error specifications based on a current configuration of the respective hardware module. The measurement device then calculates an uncertainty associated with the measurement or measurements based on the error specifications.
