ABSTRACT:
A delayed sweep oscilloscope having a word recognizer displays multi-digit parameters representing an event count necessary to initiate a delayed sweep, and a word to be recognized on oscilloscope data input lines. The numbers are modified digit-by-digit by rotating a first control knob to move a cursor on the screen to select a digit to be altered and then by rotating a second control knob to alter the selected digit. The control knobs are mounted on the oscilloscope front panel and when not used to modify these parameters, the control knobs may be used to control other oscilloscope functions.
