  • Patent number: 5574654
    Abstract: An electrical parameter analyzer analyzes samples of electrical power by executing program instructions stored on a PCMCIA compatible program card. The analyzer has a central processing unit including a microprocessor which reads the program card and passes program instructions to an acquisition control processor and an input/output controller, each of which has its own microprocessor. A series of values for a characteristic parameter of the electrical power are generated by the acquisition control processor, and these values are printed under control of the input/output controller upon request of the central processing unit.
