Abstract

PURPOSE: To prevent the setting and reading mistakes of a trigger pattern setting switch by providing both a detecting function for detecting the OFF condition of the switch and a warning function for displaying the output of the same.
CONSTITUTION: The output lines 51W54 of a trigger pattern setting switch 7 generate, in case they are set at HIGH or LOW, the logic signals corresponding thereto. A logic value 1 is obtained from output lines 55W58 in case the trigger pattern is set at OFF. As a result, an OR circuit 31 generates a logic value 1 in case at least one of the switch 7 is set at OFF. The output signal 61 is fed to a character generator 10 and an X.Y signal 11 so that a warning signal is displayed in a CRT 12. Thus, the mistake of the switch 7 can be prevented when the data of a logic scope are written.
