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
inputs.

. 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.

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

operation
may
cause
malfunction
to
the
instrument.
Do
not
use
the
provided

VERT MODE: (Hereinafter referred to as V.MODE).
The sweep trigger source is selected with the
MODE selector for the vertical operation (Y-

to CH1, the channel-1 signal is used as a trig-
ger source. When it is set to CH2, thechannel-2
signal is used as a trigger source. When set to
ALT, both the channel-1 and channel-2 signals
are used alternately. When set to CHOP or ADD,
the channel-1 signal is used as a trigger source.
Channel 1 signal is used as a trigger source.
Channel 2 signal is used as a trigger source.
Sweep is triggered by line voltage (5O/60 Hz).

* 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 positinn, a part of
the input signal fed to the INPUT jack ® or (0 is ap-
plied from the vertical amplifier to the tigger circuit
to cause the trigger signal synchronously with the
input signal to drive the sweep circuit. If ine SOURCE
select switch is set to V.MODE, the tigger signal
is selected in compliance with the vertical MODE
selector setting. (Refer to the section ‘(CONTROLS
AND INDICATORS’’.) Setting the venigical MODE
selector to ALT causes independent trggger to the
channel-1 and channel-2 signals respectively, ena-
bling two signals with no time relationsti p to be ob-
served.
if the SOURCE select switch is set to C-41 or CH2,
triggering is made by the channel-1 ani channel-2
signals respectively, regardless of MODE 7 setting.
Setting the SOURCE select switch to SNE causes
synchronization with commercial powerffrequency.

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.

The
trigger
signal
is
supplied
through
a
low-pass
filter
to
eliminate
the

* Auto Trigger
When the TRIG MODE @ 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 contro! for obser-
vation as in the normal trigger signal. When the trig-
ger level exceeds the trigger signal, the tigger 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 mo sweep.
* Fix
When the TRIG MODE @9 is set to FIX, triggering is
always effected in the center of the waveform,
eliminating the need for adjusting the tiggering lev-
el. As shown in Fig. 11-(a) or (b), wher the TRIG
MODE is set to NORM and the triggering Bevel 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 levelis automati-
cally adjusted to the approximate centerof the wave-
form and the signal is synchronized regadiless of the
position of LEVEL control as shown inF ig. 11-(c).
When the input signal is suddenly chagged from a
square waveform to a pulse waveforn, the trigger
point is shifted extremely toward the ’—" side of
the waveform unless the triggering levelis readjusted
as shown in Fig. 12-(a).
See Fig 12-(a)-(2). Also, if the trigger ptm t has been
set to the ‘’—’’ of squarewave (Fig 12(b>)-(1)) and
the input signal is changed to a pluse sinaal, the trig-
ger point is deviated and the sweep stop. When this
happens, set the TRIG MODE to FIX anit he trigger-
ing is effected in the approximate centeryf the wave-
form, making it possible to observéa Stabilized

(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 anormal wave-
form display.
2. Depress the HOLD OFF control @ (AFTER DELAY) and
set the HORIZ MODE to ALT. Adjust TRACE SEPATA-
TION @) for easy observation of both the Aand 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 4 REF/DELAY TIME POSITION @) contra can be used
to continuously slide the magnified portionof 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, appaent jitter in-
creases as magnification increases. To obtan a jitter free
display pull the HOLD OFF control out. In this ‘‘Trigger-
able After Delay’’ mode the A trigger signa 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
the
amount
of
horizontal
deflection
with
the
CH2
VOLTS/DIV
and
VARIABLE
controls.
4.
The

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
viewving
of
ver-
tical
fields
and
frames
of
video.
When
observing
the
video
waveforms,
stable
display
is
obtained
on

if
the

switch
to
FIX.
At
most
points
of
measurement,
a
compositevideo
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
postive
and
the
video
is
negative.
In
this
case,
use
‘’+’’
SLOPE.

(6) SINGLE SWEEP OPERATION
This mode of display is useful for looking at non-
synchronous or one time events.
Procedure:
1. 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.
2. 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.
3. 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.
NOTE:
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 (8) clock-
wise up to 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 (1). The sweep scale factor is displayed in
the lower right part. By pulling the < » POSITION/
PULL x 10 MAG switch @, 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.
2 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 G) 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 @.

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 AV1.
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 @) 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.
