Abstract

PURPOSE: To distinctly identify the echo pulses of defects on a screen, by displaying the desired observation range by two bright lines rectangular to a time base while indicating a detecting level by the height of the bright lines.
CONSTITUTION: Transmission pulses, defective echo pulses, base echo pulses, etc. sent out from a video amplifier appear on a screen of a Braun tube B. Monostable multivibrators M1, M2 forward square waves with the desired time width, and monostable multivibrators M3, M4 send out the first and second pulses substantially shown by one line. The pulses are added to a level regulator L through a resultant circuit H2, and further added to the Braun tube B through a resultant circuit H1. When there are defective echo pulses, an alarm device D gives alarms.
