Claims

[Scope of utility model registration request]

In an oscilloscope that uses a CRT, there is a switching circuit that switches between the input signal and the O-volt signal, a sawtooth wave generation circuit that drives the switching circuit, and an output signal from the sawtooth wave generation circuit that turns the CRT's electron beam on and off. 1. A CRT oscilloscope comprising a brightness control circuit, which displays an input signal during a sweep period, and displays an O volt signal during a retrace period.
