ABSTRACT:
Compact oscilloscope in which the display, an array of light emitting diodes, is integral with the probe. The array continuously is scanned column by column at a controllable rate and concurrently voltages are applied to rows selected in accordance with the amplitude of the test waveform. Light is emitted from those diodes of the array receiving coincident row and column excitation to thereby display the test waveform.
