C H 1 V OLTS/DIV a nd CH 2 V OLTS/DIV
Switches-
Used to select the vertical deflection factor
in α 1-2-5
sequence . To obtain α calibrate d d
eflection factor, the
V OLTS/DIV variable control must be in the
calibrated
(CAL) d etent (fully clockwise) .
1X-Indicates the deflection factor
selected w hen
using either α 1 Χ probe or α coaxial
cable .
10 Χ PROBE-Indicates t he d eflection
factor se-
lected
when using α 10 Χ probe .
V
OLTS/DIV Variable Controls-When rotated
coun-
terclockwise out of their calibrate d detent
positions,
these controls provide continuously variable,
uncalibrated deflection factors between the
calibrated
settings of the V OLTS/DIV switches .
P OSITIONControls-Use d
to vertically p osition the
display on the crt .
When t he SEC/DIV switch is set to
Χ - Υ , the Channel 2
P OSITION control moves the dis-
play vertically (Y-axis),
an d t he H orizontal P OSITION
control moves the d isplay
h orizontally (X-axis) .

Input Coupling
(AC-GND-DC)
Switches-Three-po-
sition switches that select the method of cou p
ling the
input
signals
to
the instrument d eflection system .
AC-Input signal is capacitively coupled to the ver-
tical amplifier . The do component of the input sig-
nal is b locked .
L ow-fre
q
uency limit (-3 dB point) is
approximately
10 Hz .
G ND-The
input
of
the vertical amplifier is
grounded to p rovide α zero (ground)
reference-volt-
age dis p lay ( d oes
not
ground
the input signal) . This
switch position allows p recharging
the input cou-
pling cap acitor .
DC-All frequency
components of the input signal
are cou p led to the vertical
deflection systems .

VERTICAL MODE Switches-Two three-position
switches and two button switches are used to select
the
mo de of operation for the vertical amplifier
system
.
CH 1-Selects only
the Channel 1 in p ut signal for
dis p lay .
BOTH-Selects
b oth C hannel 1 and Channel 2 in-
put signals for display . The CH 1-BOTH-CH 2
switch must be in the BOTH p osition for either
ADD, ALT, or CHOP o peration .
CH 2-Selects only the Channel 2 input signal for
display .
ADD-Displays
t
he
algebraic sum of the Channel 1
and C
hannel 2 in p
ut
signals .
ALT-Alternately dis p lays
Channel 1 and C hannel
2 input
signals
.
The alternation occurs d uring re-
trace at theen d
of each swee p . This mode is useful
for
viewing b oth i nput signals at sweep speeds
from
0 .05
)us per division to 0 .2 ms per division .
CHOP-The display switches
between the Chan-
nel 1 and Channel 2 input
signals during the
sweep .
The switching rate is
approximately
500
kHz . This mode is useful for
viewing b oth
C hannel 1 and
Channel 2 input signals at sweep
