@ V O L T S / D S V Control
Vertical attenuator for channel 1 . Provides step adjust-
ment of vertical sensitivity in 1-2-5 sequence.
A B L E control is turned to the C A L position, the
calibrated vertical sensitivity is obtained.
operation, this control serves as the attenuator
Y axis.
@ V A R I A B L E / P U L L X 5 G A I N Controls
V A R I A B L E :
Rotation provides fine control of C H 1 vertical sensi-
tivity. In the fully clockwise ( C A L ) position, the
vertical attenuator is calibrated. For X - Y operation,
this control serves for X-axis attenuation fine adjust-
ment.
P U L L X 5 G A I N :
When pulled out, the V O L T S / D I V setting is multiplied
by five, and for X - Y operation, the X-axis sensitivity
is multiplied accordingly. In X 5 G A I N mode, increas-
ed vertical gain makes the trace thiker.
@ y POSITION Control
Rotation adjusts vertical position of C H 1 waveform on
the screen. For X - Y operation, this control adjusts Y
axis position.
In memory scope operation, the control provides D C
O F F S E T adjustment of C H 1 , superimposing the D C
level over input signal.
Clockwise rotation of the control adds +DC level to the
G N D level. Counterclockwise rotation adds - D C level
to the G N D level.

Selects the coupling of channel 2 vertical input signal.
In X - Y operation, the switch provides input selection
