Abstract

An electronic instrument includes instrument hardware, core software, and the ability to support custom data processing libraries, separate from the core software. The instrument hardware acquires unprocessed measured data. The core software includes standard measurement objects and standard algorithms. The standard measurement objects produce analysis results of the unprocessed measured data. The standard algorithms are used by the standard measurement objects to aid in production of analysis results of the unprocessed measured data. Custom libraries as supported by the core software include custom measurement objects and custom algorithms. The custom measurement objects produce analysis results of the unprocessed measured data. The custom algorithms are used by the custom measurement objects to aid in production of analysis results of the unprocessed measured data. The custom measurement objects also are capable of using the standard algorithms to aid in production of analysis results of the unprocessed measured data.
