FRONT PANEL
CH1 $ POSITION
®
Rotation adjusts vertical position of CH1 waveform on
the screen. For X-Y operation, this control adjusts Y
axis position.
In storage mode, this functions is the DC OFFSET ad-
justment of CH1, which superimposes a DC level over
the input signal.
Clockwise rotation of the control adds + DC level to
the GND level. Counterclockwise rotation adds — DC
level to the GND level.
(2) CH1 STORAGE POSI
Controller for adjusting the vertical position of CH1
storage waveform. In the X-Y mode, it functions as a
Y-axial position adjuster of the storage waveform.
(D
CHI VOLTS/DIV
Vertical attenuator for channel 1. Provides step adjust-
ment of vertical sensitivity in 1-2-5 sequence. VARI-
ABLE control is turned to the CAL position, the
calibrated vertical sensitivity is obtained. For X-Y
operation, this control serves as the attenuator for Y
axis.
®
CH1 VARIABLE Control
Rotation provides fine control of channel 1 vertical
sensitivity. In the fully clockwise (CAL) position, the
vertical attenuator is calibrated. For X-Y operation, this
control serves as the Y axis attenuation fine adjust-
ment.

CH1 AC-GND-DC
This switch is the CH1 vertical axis coupling mode
selector, for X-Y operation, the Y-axis coupling mode
control.
AC:
AC input coupling with blocking of any DC
signal component.
GND: Vertical amplifier is disconnected from the in-
put signal and connected to ground. This mode
is useful in determining the zero reference.
DC:
DC coupling, with both the DC and AC com-
ponents of the input signal displayed on the
CRT.
(6) CH1 INPUT jack
Vertical input for channel 1 trace in normal sweep
operation. Vertical input for X-Y operation.
(7) $ CH2 POSITION/PULL INVert
• CH2 POSITION:
Rotation adjusts vertical position of channel 2
trace.
INV:
Push-pull switch selects channel 2 signal in-
verted (PULL INV) when pulled out.
(Hereafter PULL INV is described as CH2 INV.)
(8) CH2 STORAGE POSI
Controller for adjusting the vertical position of CH2
storage waveform. In the X-Y mode, it functions as an
X-axial position adjuster of the storage waveform.
