This document describes briefly the history and current state of development of the Real Time Executive (RTE) Modal Program. The purpose of this document is to provide a reference for the operation of the RTE Modal Program and to provide a reference for future program development. The RTE Modal Program has been developed as a replacement of an earlier program (User Program 9) that was written for the HP-5451-B Fourier system. The original concept of an RTE based program began in 1978 but was not realized in a working form until early in 1981. Based on the operating system of the HP-5451-B, Basic Control System (BCS), continued expansion of that software is prohibitive due to the inflexible programming environment and the memory limitations. To address these problems, the RTE Modal Program utilizes the overhead functions of the File Management Program under (RTE), an operating system available on Hewlett Packard computers, to provide flexibility that does not have to be built into the modal software. The emphasis of the modal software development in the RTE environment is toward supportability rather than efficiency. For future development reasons and based upon the research nature of the Structural Dynamics Research Laboratory, the ability of graduate students to extend and enhance the current software is always the primary consideration. In this way, the modal software can eventually support any type of data acquisition system as well as interface through file structures to related software such as finite element analysis packages.
