<p>Testing equipment includes a display unit with a screen operating by line scanning. Line frequency pulses are added in a line counter, test values are stored in a circulation store, and delivered values are compared in a comparator which delivers a signal when a coincidence is detected. This signal is used for reproduction of a curve point on the screen. Consecutive points of horizontal or vertical lines are connected by lines released by a logic unit controlled by comparators for the n-th and (n + 1)-th test value.</p> |
