Abstract:

The incorporation of a logarithmic sweep in an oscilloscope would be useful in the study of certain timepotential changes occurring at electrode surfaces. Highquality oscilloscope circuitry was modified to accommodate experimental log adapter units. With careful adjustment, the final circuit can provide an accurate one, two, or three decade logarithmic sweep in a display range from 5 to 10,000 microsec. Inherent limitations in the oscilloscope circuitry reduce accuracy in the 1-microsec range of the log sweep. Improved performance at the initiation of the sweep is dependent upon the development of superior horizontal sweep generator and amplifier circuitry. Author
