Abstract

A method of automatic testing of systems, such as DWDM systems with an OSA, has manufacturer'"'"'s specifications loaded into the test equipment for a plurality of systems. A user selects one of the systems from a menu, and the test equipment from the manufacturer'"'"'s specification for the selected system automatically acquires data and makes measurements on the data. The results of the data are summarized in a report which indicates an overall system status, indicating where and why the system failed if any of the measurements indicates the system is out of the manufacturer'"'"'s specifications. The measurements are kept so that they may be used to determine drift when the system is tested the next time.

Claims

1. A method of automatic testing of a system comprising the steps of:

loading manufacturer'"'"'s specifications for each of a plurality of types of systems into a test equipment;

selecting one of the plurality of types of systems as the system to be automatically tested;

performing data acquisition and measurements on received data by the test equipment of the system without user intervention; and

providing a report of the status of the system by the test equipment automatically to indicate whether the system is within the manufacturer'"'"'s specifications.

2. The method as recited in claim 1 wherein the report indicates for a system failure, where the system is outside the manufacturer'"'"'s specifications, the location and reason for the system failure.

3. The method as recited in claim 1 further including the step of updating the manufacturer'"'"'s specifications in the test equipment when a new type of system becomes operational or a current type of system is updated in such a manner as to change the manufacturer'"'"'s specifications.

4. The method as recited in claim 1 wherein the measurements are retained to provide drift data in the report for subsequent tests of the system.
