SS-5710 Section 1
Specifications
1-1 GENERAL
The SS-5710 is an oscilloscope with a frequency band-
width of DC to 60 MHz that can display 8 traces on 4
channels. The SS-5710
is useful in a wide range of applica-
tions for not only production lines and maintenance and
service purposes
but also for the research and development
of a variety of electronic devices. The features of the
SS-5710 are as follows:
• In addition to display of 8 traces on 4 channels, the SS-571 0
has an ADD function for measuring the sum of two signals
and
CH 2 POLAR for measurement of the difference
between
two signals.
• Both CH 1 and CH 2 have a high deflection factor of
1 mV/div (in the x5 MAG function), which permits accurate
measurement
of lower voltages.
• The horizontal deflection system has sweep rates up to
5 nS/div (in the x10 MAG function) so that even high-speed
phenomena
can be measured with accuracy.
The SS-5710
has delayed sweep, single sweep, AL T sweep,
and X-Y operation functions, and a TV synchronizing
signal separator
circuit so that television and other com-
posite video signal waveforms can be observed.

Operating Information
2-1 OPERATING PRECAUTIONS
Observe the following precautions in operating the
SS-5710.
Ambient t1!mperature and ventilation
The SS-5710 operates normally in the ambient
temperature range of -10 °C to +50 ° C. Be sure to use
the SS-5710 within this range. Use of it outrange
can result in some trouble. Do not place anything
near the ventilating hole in the cover to block heat
dissipation.
Line voltage check
Before plugging the power cord to an electrical
output, be sure to check its voltage. The SS-571 0 can
be used
on the line voltage shown in Table 2-1,which can
be selected with
the voltage selector plug on the rear
panel. Also check
the fuse in the rear panel as shown in
Table 2-1. Operating the SS-5710 on other than the
specified voltages can result in breakdown.
Before changing
the voltage selector plug, or replacing
the fuse, be sure to unplug the power cord from the
electrical outlet.

Be sure to replace the fuses with the correct ones.
The SS-571 0 uses the fuses shown in Table 2-2 to
protect the circuits from damage by overcurrent.
If any of these fuses is burnt out, carefully determine
the cause, repair a defect if any, an.Q replace it with the
correct one. Never use fuses other then specified because
it can cause no'l
only troubles but danger.

connector ground terminals to the ground voltage part
of the object to be measured. If they are connected to
other point, the ground leads or terminals will be shorted
through the SS-5710 resulting in breakage of the meas-
uring object or the SS-5710 (including its probes).
This
must be absolutely avoided.
Do not increase light intensity excessively
Do not increase the light intensity of traces or spot
more than necessary. Excessive light intensity can not
only result in eyes fatigue but, if left for a long time,
burn the CRT phosphor surface.
Using the SS-5710 with the CRT screen up
The SS-5710 can be used with the CRT screen up as
shown in Figurer 2-2 (a). Be careful not to bring the
SS-571 0 down by pulling hard the probes connected
to the signal input connector.
2-2 OPERATION OF THE
HANDLE
The earring-handle of the SS-571 0 can be unlocked if
the rotary part (root) the handle is pused inwards (in the
arrow direction) as shown in Figure 2-2 (d).
If both the right and left ends are pushed, they can be
unlocked together, and the handle can be turned as it is.

If the rotary part is released, the handle is automatically
locked.
The handle can
be positioned as desired for carrying
(as shown in Figure 2-2 (d) ) or as stand for signal obser-
vation (as shown in Figure 2-2 (c) ).
Fold the handle back as shown in Figure 2-2 (b), if
possible, when storing the SS-5710.
2-3 CONTROLS AND SWITCHES
The functions of the switches and controls on the front
and rear panels are explained. Refer to Figure 2-3, 2-4, and
2-5.
The front panel is color-coded. The power supply, CRT,
and vertical deflection controls are dark-olive; trigger and
horizontal deflection controls are light-olive.
If the VARIABLE contols for vertical deflection factor
and sweep rate are set to other than the CAL position,
the indicator lamp lights to indicate non-calibration.
In the description of the switches, the word IN indicate
their pushed position ( .-_ ) and the word OUT their
released position (A).

INTEN
Adjust the brightness of traces or spot. Turning the
control clockwise increases intensity, and turning it counter-
clockwise decreases intensity.
BEAM FIND
Search the trace or spot positions. If the button is
pushed when a trace or spot is outside the screen, it appears
on the
CRT screen.
FOCUS
Focus traces or spot.
SCALE
Adjust the brightness scale. Turning it clockwise bright-
ens the scale, and turning it counterclockwise darkens the
scale.

ward,.
When the
control is pulled, the vertical deflection factor is
magnified 5 times.
INPUT (CH 1, CH 2)
Connector
for connecting a probe or cable to apply
input signal to be measured.
The
maximum input voltage is 400 V (DC + peak AC)
where input signals are directly applied; or 600 V (DC
+peak AC) where a probe is used.
(For the maximum input voltage where a probe is used,
refer to the instruction manual for probe.)
AC-DC (CH 1, CH 2, CH 3, CH 4)
Switch for selecting a signal input coupling.
AC: The vertical deflection input is AC-coupled. Even if AC
input signal is superimposed on DC signal, the DC compo-
nent is blocked so only the AC component is allowed to
pass.
DC: The vertical deflection input is DC-coupled. All the
frequency components, including DC,
are allowed to pass
through.
GND (CH 1, CH 2)
When the
GND position is selected, input signal is not
connected to the vertical amplifier, but the input circuit
of the vertical amplifier is grounded. (Input signal is not
grounded.) Thus, the ground voltage (normally serving
as a reference level for measurement) can be easily con-
firmed.
UNCAL (CH 1, CH 2)
If the VARIABLE control is set to other than the CAL
position, this lamp lights to indicate non-calibration.
VOL TS/DIV (CH 1, CH 2)
Set the vertical deflection factor to select one of 11
positions from 5 mV /div to 10 V /div to suit input signal
level. If the x5 MAG button is pushed in at 5 mV/div
or 10 mV/div, a high deflection factor of 1 mV/div or
2 mV/div can be obtained. The VOLTS/DIV switches
represent the voltage
(of an input signal) per division of the
scale on the CRT screen where the VARIABLE control is
set to the CAL position.

connectors are displayed on the CRT screen. This mode is
suitable for observing waveforms where TIME/DIV is set to
a position faster than 1 msec/div.
CHOP: The two signals applied to CH 1 and CH 2 INPUT
connectors are displayed on the CRT screen. This mode is
suitable for observing waveforms where TIME/DIV is set
to a position slower than 1 msec/div.
ADD: The ADD mode is selected when both CH 1 and CH
2
buttons are simultaneously pushed in. This mode is used
for observing the algebraic sum of the signals applied to CH
1 and CH 2 INPUT connectors or their difference. CH 1
±
CH 2 can be selected with CH 2 POLAR.
QUAD: If the QUAD button is IN when the AL Tor CHOP
button is IN position, quadruple traces are displayed on
the
CRT screen. This mode is used for simultaneously
displaying the signals applied
to CH 1, CH 2, CH 3, and CH
4 INPUT connectors on the CRT screen. Either of the two
following quad modes can be selected.
Quad-trace display in the
AL T mode: If the AL T and
QUAD buttons are pushed in, AL T operation takes
place
to display 4 signals on the CRT screen.
Quad-trace display in the CHOP mode:
If the CHOP
and QUAD button are pushed in, CHOP operation takes
place
to display 4 signals on the CRT screen.
If the HORIZ DISPLAY ALT button is IN during the
above operations, the 4 signals
are displayed on the CRT

X-Y: A mode in which the SS-5710 is used as an X-Y scope,
CH 1 serving as X axis and CH 2 as Y axis.
MODE
This button selects either of the following trigger modes.
AUTO: In the AUTO mode, a sweep is started if trigger
condition is readied; or a free-running sweep takes place
otherwise.
NORM: In the NORM mode, a sweep is started if trigger
condition is readied; or no sweep take place otherwise.
SINGLE/RESET: The single trigger mode. This button
also has a RESET function so, no trigger signal, it puts
the
SS-571 0 into a ready condition, which is indicated
by the lighting of the READY lamp on the right.
READY
This lamp lights when the SS-5710 is in a ready state in
the single sweep mode.
---POSITION FINE (PULL x1 0 MAG)
This control has position adjusting and waveform
magnifying functions.
It has two kinds of knobs for position adjustment: The
large grey
knob for coarse horizontal position adjustment,
and the small red knob for fine horizontal position adjust-
ment. Turning the knobs clockwise moves the waveform
to the right- hand, and turning them counterclockwise
moves it to the left-hand.
When the small red knob
is pulled, the x1 0 MAG func-
tion is set to magnify the waveform 10 times in the hori-
zontal direction.
COUPLING (A-Sweep)
For selecting an A-sweep trigger coupling (trigger circuit
input coupling).
AC: AC coupling
is selected. Trigger signal DC component
is blocked. AC signal only is used for triggering.
DC: DC coupling is selected. DC can be used for triggering.
HF REJ: Frequencies over
approximately 10 kHz are
attenuated by a lowpass filter. Suitable for observing signals
cleared of high-frequency noise.
LF REJ: Highpass
filter coupling to attenuate low fre-
quencies under approximately 10 kHz.
Suitable
for observing signals cleared a low-frequency
noise.

SS-5710
FIX: If both the AC and DC buttons are simultaneously
pushed in, the trigger level
is fixed nearly at the zero point.
Thus, it is not necessary to operate the LEVEL control.
TV-H: If both the DC and HF REJ buttons are simulta-
neously pushed in, TV-H coupling is selected. This trigger
coupling is used for ovserving a composite video signal
waveform over a period
of 1 H by triggering with a televi-
sion horizontal trigger pulse.
TV-V: If both the HF REJ and LF REJ buttons are simul-
taneously pushed in, TV-V coupling is selected. This
trigger coupling
is use<;J for observing a composite video
signal waveform over a period
of 1 V by triggering with
a television vertical trigger pulse.
SOURCE (A-Sweep)
Select the SOURCE of A-sweep trigger signal.
CH 1: The input signal applied to CH 1 INPUT is branched
out as internal trigger signal.
CH 2: The input signal applied to CH 2 INPUT is branched
out as internal trigger signal.
CH 3: The input signal applied to CH 3 INPUT is branched
out as internal /external trigger signal.
L1 NE: The SS-571 O's power Ii ne signal is used as trigger
signals. This mode
is used for observing line signals and line
harmonics.
NORM: If both the CH 1 and CH 2 buttons are simul-
taneously pushed in, the NORM mode is selected, in which
the signal for the waveform displayed on the CRT screen
in connection
with a vertical mode is used as a trigger
signal. (For a detailed description of trigger signal selection,
refer
to the subsequent paragraph on triggering.)
HOLDOFF
This control is used for stabilized synchronization of
complex (composite) pulse waveforms. Turning the control
fully counterclockwise to NORM minimizes the holdoff
period, and turning it clockwise continuously increases the
holdoff period.
LEVEL SLOPE (PULL-) (A-Trigger, 8-Trigger)
This
control has trigger level setting and trigger slope
selecting functions.
Push it for positive-going slope trigger level selection;
or pull it for negative-going slope trigger level selection.

The outer knob is for A TIME/DIV and DELAY TIME,
and the inner knob forB TIME/DIV.
The A TIME/DIV AND DELAY TIME control has
22 A-sweep positions from 50 nsec/div to 0.5 sec/div, and
selects delays in A
INTEN sweep orB (DL Y'D) sweep.
The value
of each position of the control represents a sweep
rate and delay
time per division on the CRT screen where
the A
VAR lAB LE control is turned fully clockwise to the
CAL position.
The B
TIME/DIV control has 19 B-sweep positions
from 50 nsec/div to 50 msec/div, but no VARIABLE control.

brating state when A
VARIABLE control is out of CAL
position.
DELAY TIME MULT
This potentio-meter selects the amount of delay time
between the start
of A sweep and the start of B sweep.
Section 2 Operating Information
COUPLING (B-Sweep)
For selecting a B-trigger coupling (trigger circuit coup-
ling).
If the DC and HF REJ buttons are simultaneously
pushed in,
TV-H is selected.
All functions are the same as those of A-sweep except
for LF REJ, TV-V and FIX.
SOURCE (8 -Sweep)
The SOURCE
buttons are used for selecting 8-sweep
trigger signals and a
type of delay (continuous delay or
triggered delay).
RUNS AFTER DELAY: When the button is IN, RUNS
AFTER DELAY is selected for continuous delay.
CH 1: Function is the same as that of A-sweep.
CH 2: Function is the same as that of A-sweep.
CH 4: The input signal applied to CH 4 INPUT is branched
out as trigger signal. This function corresponds to the
external trigger
function of a dual-trace oscilloscope.
(If the CH 1, CH 2, or CH 4 button is pushed in, the
triggered delay mode
is selected.)
t TRACE SEPARATION
This controi is used for moving the B-sweep waveform
above the A INTEN sweep waveform on the CRT screen
when the
HORIZ DELAY button AL Tis IN. If the contol
is turned fully counterclockwise, the A INTEN sweep and
