Abstract
PURPOSE: To display the monitor window of arbitrary X-coordinate and arbitrary Y-coordinate on a cathode ray tube screen by overlapping with signal waveform, and to issure an alarm by comparing the arbitrarily set monitor window with the signal amplitude.
CONSTITUTION: Digital X-coordinate generated in control circuit 1 is added to one input of comparator circuits 7, 8, and X-coordinate values X1, X2 set in counters 9, 10 are applied to the other input. When the X-coordinates are scanned from 0 to the maximum value, Y-coordinates showing the signal wave are forwarded accordingly, and the signal waveform is displayed in the cathode ray tube. At this time, coincidence signals are sent into the circuit 1 from comparator circuits 7 and 8, respectively, to X=X1 and X=X2. At the same time, in the range of X1<X<X2, the switch 14 is closed, and the value of Y-coordinate in this period is compared with voltage YL, and an alarm signal is sent out into the comparator 15 when Y>YL. Then, the switch 5 is changed over, and the coordinates are scanned from X1 to X2, and displayed in the window. This display to be overlapped with the signal waveform to the eye of the observer.
