In put Cou p ling (AC-GND-DC) Switches-Used to
select the method of coupling input signals to the

AC-Input signal is capacitively coupled to the
vertical amplifier . The d o component of the input
signal
is
b locked .
L
ow-frequency limit
(-3

B
p oint) is a pp roximately 10 Hz .

(groun
d )
reference-
voltage
d
isplay (does
n
ot
groun d the input signal) .
This switch p
osition allows precharging the input
cou p ling cap acitor .
DC-All frequency components of the input
signal are couple dto the vertical d eflection system .
CH 1 V OLTS/DIV and CH 2 V OLTS/DIV
Switches-
Used to select the vertical d
eflection
factor
in α 1-2-5
se q uence . To obtain α calibrated d eflection factor,
the VOLTS/DIV variable control must be in detent .
1 Χ PROBE-Indicates the deflection factor
selected when u sing either α 1 Χ p robe or α coaxial
cable .
10 Χ PROBE-Indicates t he d eflection factor
selected when using α 10 Χ probe .
V OLTS/DIV Variable Controls-When rotated coun-
ter
clockwise out of their detent positions, these
controls provide continuously variable, uncalibrated
deflection factors between the calibrated settings of
the V OLTS/DIV switches . E xtends maximum uncali-
brated deflection factor to 25 volts per division with IX
probe ( α range of at least 2 .5 :1) .
I NVERT Switch-Inverts the Channel 2d isplay when
button is pressed in . Push button must be pressed
in α second time to release it and regain α noninverte d
dis p lay .
VERTICAL MODE Switches-Two
three-position
switches
are
used to select
the mode
of
operation for
the vertical
amplifier
system
.
CH 1-Selects only
the Channel
1
input signal for
d isplay .
BOTH-Selects both C
hannel
1 and
C hannel 2
input signals for display . The BOTH p osition must
be selecte d for either ADD, ALT, or CHOP
operation .
CH 2-Selects only the
Channel
2input
signal for
display .
ADD-Dis p lays the algebraic sum of the Channel 1
an d Channel 2 input signals .
ALT-Alternately d is p lays
Channel 1 and
C
hannel
2 input signals . The alternation occurs during
retrace at the end of each sweep . This
mo de
is useful for viewing b oth i nput
signals
at
swee p
s peed s from 0 .05 μ s p er d ivision to 0 .2 ms
per
division .
C HOP-The dis p lay switches b etween the Chan-
nel 1 and Channel 2 input signals during the
sweep . The switching rate is a p proximately 250
kHz . This mo d e is u seful for viewing both C hannel
1 and Channel 2 in put signals at sweep s p eeds
from 0 .5 ms p er d ivision to 0 .5 s p er d ivision .
P OSITION Controls-Use d to vertically p osition the
display on
the crt . When the SEC/DIV switch is set to
Χ - Υ , the Channel 2P OSITION control moves the
d isplay vertically (Y-axis), and the H orizontal
P OSITION control moves the d isplay h orizontally
(X-axis) .
