1. An electronic instrument comprising: instrument hardware for acquiring unprocessed measured data; core software, the core software including: standard measurement objects that produce analysis results of the unprocessed measured data, and standard algorithms that are used by the standard measurement objects to aid in production of analysis results of the unprocessed measured data; and, a custom library, separate from the core software, the custom library including: custom measurement objects that produce analysis results of the unprocessed measured data, and custom algorithms that are used by the custom measurement objects to aid in production of analysis results of the unprocessed measured data; wherein the custom measurement objects also are capable of using the standard algorithms to aid in production of analysis results of the unprocessed measured data.
