Microphonics Test Station

摘要

The methodology of arriving at the final microphonics test station was the classical approach. There was a conceptual design followed by a paper design. New circuitry was breadboarded and tested. These circuits were then fabricated and performance tested. Integration of completed and integration tested. This classical approach was backed up by a number of alternatives should any technical problem create either a schedule or cost risk. For example, a Spectral Dynamics SD1200A was available for use as a controller should the Honeywell design encounter a significant problem. The control software also existed for the SD1200A and this became the fall back position for the software effort. The development of a triaxial exciter was a natural follow-on to the development and use of a single axis piezo-electric exciter undertaken in the M1 microphonics effort. The initial concern that a piezo-electric exciter may not have sufficient response at the low end of the frequency spectrum was proven to be unfounded.
