Variable color comparison oscilloscope
First Claim
1. A method of simultaneously displaying a measured waveform and its relation to predetermined limits, on a single variable color display means, by causing said waveform to be exhibited on said display means, and by controlling the color of the exhibited waveform in accordance with its relation to said limits such that portions of the exhibited waveform that are within said limits are displayed in a first color, and portions of the exhibited waveform that are outside said limits are displayed in a second color.

Abstract
A waveform measuring device includes a variable color display for exhibiting a measured waveform. The portions of the exhibited waveform that are within predetermined limits are illuminated in a first color, and the portions of the exhibited waveform that are outside the limits are illuminated in a second color.
