FRONT PANEL
CH1 4 POSITION Control
Rotation adjusts vertical position of CH1 waveform on
the screen. In X-Y operation, rotation adjusts vertical
position of display.
CH1 VOLTS/DIV Control
CH1 VARIABLE
Control
Rotation provides fine control of channel 1 vertical sen-
CH1 AC-GND-DC Switch
ponents of the input signal displayed on the CRT.

# CH2 POSITION/PULL INVert Control
* CH2 POSITION:
Rotation adjusts vertical position of channel 2
trace.
Push-pull switch selects channel 2 signal in-
verted (PULL INV) when pulled out.
(Hereafter PULL INV is described as CH2 INV.)
INV:
CH2 VOLTS/DIV Control
Vertical attenuator for CH2. Provides the same func-
tion as VOLTS/DIV Control @ for CH1.
In X-Y opera-
tion, the control serves as the X-axis attenuator.
CH2 VARIABLE Control
Rotation provides fine control of channel 2 vertical sen-
sitivity.
Provides the same function as VARIABLE Costrol @) for
CH1.
In X-Y operation, this control serves
for ><-axis at-
tenuation fine adjustment.
CH2 AC-GND-DC Switch
Three-position lever switch which operates is follows:
AC:
Blocks DC component of channel 2 input signal.
GND:
Opens signal path and grounds inputt 0 vertical
amplifier. This provides a zero-signalbase line,
the position of which can be used as reference
when performing DC measurement:
DC:
Direct input of AC and DC component of chan-
nel 2 input signal.
