T h i s is the vertical attenuator. It is used to attenuate
a signal voltage fed to A C terminal (1) or D C terminal
(3) to the amplitude suited for observation on C R T
screen.
When it is set to the 1 position, the signal fed to A C
terminal (1) or D C terminal (3) is directly fed to the
vertical amplifier. A t the 1/10 or 1/100 position, the
waveform amplitude is reduced to 1/10 or 1/100. A t
the G N D position, the input of the vertical amplifier
is connected to the earth.
