Abstract
The apparatus for displaying a clamp point on a screen includes an input amplifier; a clamp circuit which includes a sync separation circuit and a one shot; and a blanking circuit. The video signal is applied to the clamp circuit via the input amplifier and the output signal therefrom is applied to the blanking circuit to be modulated with respect to its brightness. Thus, the brightness-modulated clamp point is readily located on a screen of, for example, an oscilloscope.
