Abstract :
A flexible, modular multichannel continuous real-time harmonic analyzer with the capability of precision time stamping via Global Positioning System (GPS) satellite signals of the acquired data is described. The key design features which provide this performance are discussed. These include remote distributed data conversion modules coupled via digital fiber-optic links to parallel individual digital signal processor Multibus II based modules which were all controlled by a highly integrated 486 based module. The resultant Multibus II parallel processor system was run under the iRMXIII real-time operating system and was interfaced via Ethernet to control and display workstations using a custom-designed Windows 3 environment. The ready extension of the harmonic monitoring system to transient measurement is also described
