Vertical axis attenuator for channel 2. Performs the same function for channel 2 a s
the channel 1 V O L T S / D I V control. S e r v e s as the X axis or Y axis attenuation adjust-
ment control during X - Y operation.
© V A R I ( A B L E )
Rotation provides fine control of channel 2 attenuation. Performs the same function
for channel 2 as the channel 1 V A R I A B L E control. S e r v e s a s the X axis or Y axis at-
tenuation fine adjustment control during X - Y operation.

This lever selects the coupling method used for the channel 2 vertical axis input signal.
Performs the same function as the channel 1 A C - G N D - D C control. Serves as the Y axis
or Y axis input selector during X - Y operation.
© C H 2 INPUT
Vertical axis input jack for channel 2 . S e r v e s as the X axis or Y axis input jack during
X - Y operation.
@ V o r Y MODE
T h i s s w i t c h selects the vertical axis operation mode and serves as the Y axis selection
s w i t c h during X - Y operation.
C H 1 :
Channel 1 input signal is displayed on the C R T . Channel 1 is the Y axis if this
mode is selected during X - Y operation.
C H 2 :
Channel 2 input signal is displayed on the C R T . Channel 2 is the Y axis if this
mode is selected during X - Y operation.
A L T :
Channel 1 and channel 2 signals are displayed alternately on the C R T w i t h
each s w e e p .
CHOP:
Channel 1 and 2 signals are displayed alternately on the C R T at a repetition
rate of 5 0 kHz or more.
ADD:
The algebraic sum of the channel 1 and 2 signal is displayed on the C R T . If
C H 2 INV © is engaged, the difference is displayed on the C R T .
Note:
The A L T , CHOP, and ADD modes cannot be used during X - Y operation.
© C H 2 INV
Inverts the polarity of the channel 2 signal.

T h i s button selects the trigger source w h e n an internal trigger (INT) is selected. S e r v e s
as the X axis selection s w i t c h during X - Y operation.
C H 1 :
Channel 1 input signal serves as the trigger source. Channel 1 becomes the
X axis if this button is pressed during X - Y operation.
C H 2 :
Channel 2 input signal serves as the trigger source. Channel 2 becomes the
X axis if this button is pressed during X - Y operation.
