The ON/OFF switch. Push to switch the unit ON.
@ INTENSITY/PULL TRACE ROTATION Control
INTENSITY
: Used to adjust the brightness of the
beam trace.
: When
the knob is turned
in the
pulled-out position, it adjusts the
inclination of the horizontal trace
line. Used to adjust for deviations
resulting from the effects of the
Earth's magnetic field.
TRACE ROTATION
@ FOCUS/PULL ASTIG Control
FOCUS
: Used for focal adjustment.
ASTIG
: When turned in the pulled-out po-
sition, adjusts the convergence of
the beam. Used together with FO-
CUS
to
obtain
crisp,
clear-cut
waveforms.

© ATT 1/100, 1/10, 1 Switch assembly
Used for adjusting input levels of vertical amplifier in the
oscilloscope and bandscope modes. When set to '1,"'
the signals input into INPUT ©) are passed directy into
the vertical amplifier. When set to '1/10' or ''1/100,"
the signals are attenuated and the amplitude of the wave-
form on the monitor is reduced to 1/10 or 1/100, respec-
tively.
(Displayed

@ GND AC/DC Switch
The switch that selects the coupling mode for the verti-
cal input signals in the oscilloscope mode.
GND:
The input signals and the vertical amplifier are iso-
lated from each other and the amplifier input is
grounded. In this way, the ground potential can
be verified.
AC:
The input signals are AC-coupled, and DC com-
ponents are removed.
:
DC_:
The input signals are DC-coupled, and observa-
tion can be performed with the DC components
included.
Note:
When the GND switch is depressed, GND receives pri-
ority over AC/DC and the vertical amplifier input is
grounded.
