PRECAUTIONS
SAFETY
Before
connecting
the
instrument
to
the
power
source,
care-
fully
read
the
following
information,
then
verify
that
the
power
cord
and
power
line
fuse
are
ones
for
your
power
line.
The
instrument's
rear
panel
has
a
fuse
holder
on
the
left
of
the

inlet
terminal
(the
fuse
holer
also
serves
as
a
vol-
tage
selector).
The
value
under
the
triangle
V
marked
on
the
holder
indicates
the
line
voltage
set
for
the
instrument.
lf
the
power
cord
is
not
applied
with
the
correct
voltage,
there is a danger from electric shock.
®
When
converting
the
voltage,
refer
to
the
Maintenance
section.
Line voltage
This
instrument
operates
using
ac-power
input
voltages
that
100/120/220/240
V
at
frequencies
from
50
Hz
to
60
Hz.
Power cord
The
ground
wire
of
the
3-wire
ac
power
plug
places
the
chassis
and
housing
of
the
oscilloscope
at
earth
ground.
Do
not
attempt
to
defeat
the
ground
wire
connection
or
float
the
oscilloscope;
to
do
so
may
pose
a
great
safety
hazard.
The
appropriate
power
cord
is
supplied
by
an
option
that
is
specified
when
the
instrument
is
ordered.
:
The
optional
power
cords
are
shown
as
follows
in
Fig.
1.
Line fuse
The
fuse
holder
is
located
on
the
rear
panel
and
contains
the
line
fuse.
Verify
that
the
proper
fuse
is
installed
by
replacing
the
line
fuse.
EQUIPMENT PROTECTION
1.
Never
allow
a
small
spot
of
high
brilliance
to
remain
sta-
tionary
on
the
screen
for
more
than
a
few
seconds.
The
screen
may
become
permanently
burned.
A
spot
will
occur
only
when
the
scope
is
set
up
for
X-Y
operation
and
no
signal
is
applied.
Either
reduce
the
intensity
so
the
spot
is
barely
visible,
switch
back
to
normal
sweep
operation
when
no
signal
is
applied,
or
set
up
the
scope
for
spot
blanking.
2.
Never
cover
the
ventilating
holes
on
the
top
of
the
os-
cilloscope,
as
this
will
increase
the
operating
tempera-
ture
inside
the
case.
3.
Never
apply
more
than
the
maximum
rating
to
the
os-
cilloscope

Always
connect
a
cable
from
the
earth
ground
(GND)
jack
of
the
oscilloscope
to
the
chassis
of
the
equipment
under
test.
Without
this
caution,
the
entire
current
for
the
equipment
under
test
may
be
drawn
through
the
probe
clip
leads
under
certain
circumstances.
Such
con-
ditions
could
also
pose
a
safety
hazard,
which
the
ground
cable
will
prevent.
.
Always
use
the
probe
ground
clips
for
best
results.
Do
not
use
an
external
ground
wire
in
lieu
of
the
probe
ground
clips,
as
undesired
signals
may
be
introduced.
.
Operation
adjacent
to
equipment
which
produces
strong
ac
magnetic
fields
should
be
avoided
where
possible.
This
includes
such
devices
as
large
power
supplies,
transformers,
electric
motors,
etc.,
that
are
often
found
in
an
industrial
environment.
Strong
magnetic
shields
can
exceed
the
practical
CRT
magnetic
shielding
limits
and
result
interference
and
distortion.
.
Probe
compensation
adjustment
matches
the
probe
to
the
input
of
the
scope.
For
best
results,
compensation
of
probe
should
be
adjusted
initially,
then
the
same
pro-
be
always
used
with
the
input
of
scope.
Probe
compen-
sation
should
be
readjusted
whenever
a
probe
from
a
different
scope
is
used.
(See
page
21)
.
In
X-Y
operation,
do
not
pull
out
the
PULL
x
10
MAG
switch.
If
pulled
out
it,
noise
may
appeare
on
the
waveform.
.
When
turning
on
and
off
the
POWER
switch
repeated-
ly,
keep
an
interval
of
about
5
seconds.
Faster
on
and
off
operation
may
cause
malfunction
to
the
instrument.
Do
not
use
the
provided
PC-33
Probe
with
other
meas-
uring
equipment
because
it
incorporates
4
terminal
for
READOUT
detection
which
might
damage
the
other
equipment.

[A] OPERATION AS A GENERAL-USE OSCIL-
LOSCOPE
(1) Normal sweep display operation
1. Press the POWER switch (5 to supply power, and the
POWER LED (6 lights.
2. A bright line appears in the CRT center. If it is not in the
center, adjust its position to the center with the ¥ POSI-
TION controller @). Then, adjust the brightness with the
INTENSITY controller (2), and the focus, with the FOCUS
controller as required for easy observation.
3. Supply input signal into the CH1 INPUT jack ©). Rotate
the VOLTS/DIV control @ to adjust waveform to ap-
propriate dimensions.
Set the MODE select switch (1) to CH2. Then, supply in-
put signal into the CH2 INPUT connector (2. Its wave-
form is displayed on the CRT in the same procedures with
channel 1.
When the MODE select switch is set to ADD, the com-
posite waveforms of CH1 and CH2 (the algebraic sum
of CH1 + CH2) is displayed on the CRT. In this status,
if CH2 INV is engaged by pulling out the CH2 ¥ POSI-
TION, the algebraic difference between CH1 and CH2
(CH1 - CH2) will be displayed.
The sensitivity of the ADDed waveform becomes the
same as the value indicated by VOLTS/DIV provided that
the same VOLTS/DIV value has been set for the wave-
forms of the two channels.
When the MODE select switch (i) is set to ALT, the
channel-1 and channel-2 waveforms are displayed alter-
nately in every sweep. Waveform of each channel is trig-
gered independently. If the MODE select switch @ is set
to CHOP, channel-1 and channel-2 waveforms through
chopped triggering are displayed. If the SOURCE select
switch @ is set to V. MODE, the channel-1 signal only

the SOURCE select switch @ to CH2.
. The display on the screen will probably be unsynchroniz-
ed. Refer to TRIGGERING procedure below for adjusting
synchronization and sweep speed to obtain a stable dis-
play showing the desired number of waveform.
TRIGGERING
The input signal must be properly triggered for stable
waveform observation, TRIGGERING is possible the in-
put signal INTernally to create a trigger or with an EX-
Ternally provided signal of timing relationship to the
observed signal, applying such a signal to the EXT. TRIG
INPUT jack @.
(1) The selection of a signal that serves as the trigger
signal is made using the SOURCE switch @.
* Internal Sync
When the SOURCE selector is set to V.MODE,
CH1, CH2 or LINE, the input signal is connected to
the internal trigger circuit. In this position, a part of
the input signal fed to the INPUT jack (©) or @ is ap-
plied from the vertical amplifier to the trigger circuit
to cause the trigger signal synchronously with the
input signal to drive the sweep circuit. If the SOURCE
select switch is set to V.MODE, the trigger signal
is selected in compliance with the vertical MODE
selector setting. (Refer to the section “CONTROLS
AND INDICATORS”’.) Setting the vertical MODE
selector to ALT causes independent trigger to the
channel-1 and channel-2 signals respectively, ena-
bling two signals with no time relationship to be ob-
served.
If the SOURCE select switch is set to CH1 or CH2,
triggering is made by the channel-1 and channe!-2
signals respectively, regardless of MODE @ setting.
Setting the SOURCE select switch to LINE causes
synchronization with commercial power frequency.

After

control
@).
AC:
The
trigger
signal
is
capacitively
coupled,
so
its
DC
component
is
cut,
giving
a
stable
trigger
which
is
not
affected
by
the
DC
component.
With
this
advantage,
this
position
of
the
coupling
switch
is
conveniently
selected
for
ordinary
applications.
However,
if
the
trigger
signal
is
lower
than
10
Hz,
the
trigger
signal
level
becomes
attenuated,
resulting
in
difficulty
in
triggering.
HF Rev:
The
trigger
signal
is
supplied
through
a
low-pass
filter
to
eliminate
the
high-frequency
component
(higher
than
10
kHz),
giving
a
stable
triggering
with low-
frequency
component.
When
high-frequency
noise
is
superimposed
over
the
trigger
signal
as
shown
in
Fig.
9,
the
high-frequency
noise
is
cut
to
provide
a
stable
trigger.

* Auto Trigger
When
the
TRIG
MODE
@9
selection
is
in
AUTO,
the
sweep
circuit
becomes
free-running
as
long
as
there
is
no
trigger
signal,
permitting
a
check
of
GND
lev-
el.
When
a
trigger
signal
is
present,
the
trigger
point
can
be
determined
by
the
LEVEL
control
for
obser-
vation
as
in
the
normal
trigger
signal.
When
the
trig-
ger
level
exceeds
the
trigger
signal,
the
trigger
circuit
also
becomes
free-running
where
the
waveform
starts
running.
When
the
TRIG
MODE
is
set
to
NORM
and/or,
when
the
trigger
signal
is
absent
or
the
trig-
gering
level
exceeds
the
signal
there
is
no
sweep.
* Fix
When
the
TRIG
MODE
@)
is
set
to
FIX,
triggering
is
always
effected
in
the
center
of
the
waveform,
eliminating
the
need
for
adjusting
the
triggering
lev-
el.
As
shown
in
Fig.
11-(a)
or
(b),
when
the
TRIG
MODE
is
set
to
NORM
and
the
triggering
level
is
ad-
justed
to
either
side
of
the
signal,
the
trigger
point
is
deviated
as
the
input
signal
becomes
small
which,
in
turn,
stops
the
sweep
operation.
By
setting
the
TRIG
MODE
to
FIX,
the
triggering
level
is
automati-
cally
adjusted
to
the
approximate
center
of
the
wave-
form
and
the
signal
is
synchronized
regardless
of
the
position
of
LEVEL
control
as
shown
in
Fig.
11-(c).
When
the
input
signal
is
suddenly
changed
from
a
square
waveform
to
a
pulse
waveform,
the
trigger
point
is
shifted
extremely
toward
the
‘’—"'
side
of
the
waveform
unless
the
triggering
level
is
readjusted
as
shown
in
Fig.
12-(a).
See
Fig
12-(a)-(2).
Also,
if
the
trigger
point
has
been
set
to
the
‘’—’’
of
squarewave
(Fig
12-(b)-(1))
and
the
input
signal
is
changed
to
a
pluse
signal,
the
trig-
ger
point
is
deviated
and
the
sweep
stops.
When
this
happens,
set
the
TRIG
MODE
to
FIX
and
the
trigger-
ing
is
effected
in
the
approximate
center
of
the
wave-
form,
making
it
possible
to
observe
a
stabilized
waveform.

5. Adjust the A SWEEP/TIME DIV control @ to obtain an
appropriate display. Now a normal sweep display is ob-
tained.
(2) MAGNIFIED SWEEP OPERATION
Since merely shortening the sweep time to magnify a por-
tion of an observed waveform can result in the desired por-
tion disappearing off the screen, such magnified display
should be performed using the MAGNIFIED SWEEP.
Using the <® POSITION @ control, adjust the desired por-
tion of waveform to the CRT. Pull the PULL x 10 MAG
control to magnify the display 10 times. For this type of dis-
play the sweep time is the SWEEP TIME/DIV setting divid-
ed by 10.
(3) ALTERNATE SWEEP OPERATION
A sweep and B delayed sweep are usable in an alternating
fashion making it possible to observe both the normal and
magnified waveform simultaneously.
Procedure:
1. Set the HORIZ MODE to A and adjust for a normal wave-
form display.
2. Depress the HOLD OFF control @6) (AFTER DELAY) and
set the HORIZ MODE to ALT. Adjust TRACE SEPATA-
TION @ for easy observation of both the A and B traces.
The upper trace is the non-magnified portion of the wave-
form with the magnified portion super-imposed as an
intensified section. The lower waveform is the intensi-
fied portion displayed magnified.
3. The AREF/DELAY TIME POSITION @) control can be used
to continuously slide the magnified portion of the wave-
form across the A sweep period to allow magnification
of precisely the desired portion of waveform.
4. Set the HORIZ MODE to B to display the INT intensified
portion as a magnified B sweep. (Fig. 14)
5. For Starts AFTER DELAY operation, apparent jitter in-
creases as magnification increases. To obtain a jitter free
display pull the HOLD OFF control out. In this ‘‘Trigger-
able After Delay’’ mode the A trigger signal selected by
the SOURCE switch @) becomes the B trigger source.

X-Y
OPERATION
For
some
measurements,
an
external
horizontal
deflection
signal
is
required.
This
is
also
referred
to
as
an
X-Y
meas-
urement,
where
the
Y
input
provides
vertical
deflection
and
X
input
provides
horizontal
deflection.
X-Y
operation
permits
the
oscilloscope
to
perform
many
types
of
measurements
not
possible
with
conventional
sweep
operation.
The
CRT
display
becomes
an
electronic
graph
of
two
instantaneous
voltages.
The
display
may
be
a
direct
comparison
of
two
voltages
such
as
during
phase
measurement,
or
frequency
measurement
with
Lissajous
waveforms.
To
use
an
external
horizontal
input,
use
the
following
pro-
cedure;
1.
Set
the
HORIZ
MODE
switch
to
X-Y
the
position.
2.
Use
the
channel
1
probe
for
the
vertical
input
and
the
channel
2
probe
for
the
horizontal
input.
3.
Adjust

of
horizontal
deflection
with
the
CH2
VOLTS/DIV
and
VARIABLE
controls.

VIDEO
SIGNAL
OBSERVATION
The
TV
FRAME/LINE
switch
permits
selection
of
vertical
or
horizontal
sync
pulse
for
sweep
triggering
when
viewing
composite
video
waveforms.
In
the
LINE
position,
horizon-
tal
sync
pulses
are
selected
as
triggers
to
permit
viewing
of
horizontal
line
of
video.
In
the
FRAME
position,
vertical
sync
pulses
are
selected
as
triggers
to
permit
viewing
of
ver-
tical
fields
and
frames
of
video.
When
observing
the
video
waveforms,
stable
display
is
obtained
on
the
screen
regard-
less
the
TRIG
LEVEL
@
control
if
the
TRIG
MODE
switch
to
FIX.
At
most
points
of
measurement,
a
composite
video
signal
is
of
the
(—)
polarity,
that
is,
the
sync
pulses
are
negative
and
the
video
is
positive.
In
this
case,
use
‘’—"’
SLOPE.
If
the
waveform
is
taken
at
a
circuit
point
where
the
video
waveform
is
inverted,
the
sync
pulses
are
positive
and
the
video
is
negative.
In
this
case,
use
“+”
SLOPE.

(6) SINGLE SWEEP OPERATION
This mode of display is useful for fooking at non-
synchronous or one time events.
Procedure:
1.
r-- NOTE:
Set the TRIG MODE @0 to either AUTO or NORM. Apply
a signal of approximately the same amplitude and fre-
quency as the signal that is to be observed as the trig-
ger signal and set the trigger level.
. Set TRIG MODE to RESET — observe that the READY
indicator LED lights to indicate the reset condition. This
LED goes out when the sweep period is completed.
. After the above set-up is completed the scope is ready
to operate in the SINGLE sweep mode of operation after
resetting the instrument using the RESET switch. Input
of the trigger signal results in one and only one sweep
and READY indicator LED goes out.
With the HORIZ MODE set to ALT the simultaneous
observation of the A sweep and B sweep waveforms
at SINGLE sweep mode is not possible. Also for ALT
(vertical MODE) mode operation simultaneous obser-
vation is not possible. Set the unit to the CHOP mode
in this case.
[B] READOUT OPERATION (CS-5130 only)
1
CRT surface readout
By rotating the INTEN (READOUT) controller clock-
wise upto the very end, characters are displayed on the
CRT. Adjust the brightness as necessity requires. The
CH1 and CH2 scale factors are displayed in the lower
part of the CRT in accordance with setting of the MODE
select switch @. The sweep scale factor is displayed in
the lower right part. By pulling the < » POSITION/
PULL x 10 MAG switch @9, a tenth scale factor of the A
and B SWEEP TIME/DIV control @ @ is displayed.
NOTE: When the readout values are displayed, brilliance
modulation may influence the real-time waveform
in some cases. In such a case, rotate the INTEN
(READOUT) control fully counterclockwise.
The readout function will be turned OFF, and the
brilliance modulation on the real-time waveform
will disappear.
Cursor measurement
AV1: Set the MODE select switch @ to ALT and the
CURSORS select switch @} to AV1, and two
horizontal cursor lines are displayed on the CRT
and voltage difference between cursor lines cal-
culated in accordance with setting of the CH1
VOLTS/DIV control @ is displayed in the upper
right on the CRT. By setting the CH1 VARIABLE
controller @) to the UNCAL position, voltage ra-
tio is displayed.
Move the cursors to the positions to be measured
with the AREF controller @) and A controller @.
20
AV2:
AT:
1/AT:
Set the CURSORS select switch @ to AV2, vol-
tage difference in accordance with the CH2 range
setting is displayed in the upper right on the CRT
similarly with the above AV 1.
Set the CURSORS select switch @ to AT, and
two vertical cursor lines are displayed on the CRT
and time difference between the cursor lines cal-
culated based on the A sweep scale factor dis-
played in the lower right is displayed in the upper
right. By setting the SWEEP VARIABLE controller
@) to the UNCAL position, time ratio is displayed.
Set the CURSORS select switch @3 to 1/AT, and
two vertical cursor lines are displayed on the CRT
and frequency between the cursor lines calculat-
ed based on the A sweep scale factor displayed
in the lower right is displayed in the upper right.
By setting the SWEEP VARIABLE controller @) to
the UNCAL position, phase difference is dis-
played.
