ITEMS LS 8105A LS 8106A
HOLDOFF Continuously variable from A sweep NORM position
Trace separation B sweep is continuously variable by ±4 division or more
with respect to A sweep.
Continuous delay operation (AFTER DELAY)
Delayed sweep operation Synchronous delay operation (B TRIG'D)
: Synchronous with the trigger signal
Delay time Continuous control by 0.2 to 10 divisions for 0.5 s/div.
to maximum speed sweep
Delay time error Reading on CRT ±4% ±(3% of set value + 1% of full scale)
(+10 to +35˚C) + (0 to 300 ns) + (0 to 300 ns)
Delay jitter 20000: 1 of a value 10 times as high as A sweep setting
(A sweep: 1 ms/div., B sweep: 1 µs/div.)
TRIGGERING
AUTO : Automatic free running with no signal
NORM : Triggered sweep
Trigger modes FIX : Sweep at triggering point set to center of signal amplitude
SINGLE : Single sweep mode
RESET : Restarting single sweep operation
VERT : Input signal selected for V. mode
CH1 : Channel 1 input signal
Trigger signal sources CH2 : Channel 2 input signal
CH3 : Channel 3 input signal
LINE : Commercial power line
AC : AC coupling from 10 Hz
Trigger coupling HFREJ : Low-pass filter coupling up to 10 kHz
(For trigger sensitivity, see the DC : DC coupling
table below.) TV-F (TV FRAME) : Composite video signal, vertical synchronization separation
TV-L (TV LINE) : Composite video signal, horizontal synchronization separation
MODE COUPLING Signal frequency Sensitivity (Amplitude)
NORM FIX *
AC 10 Hz to 50 MHz 1 div. 1.5 div.
50 M to 100MHz 1.5 div. 2 div.
HFREJ 10 Hz to 10 kHz 1 div. 1.5 div.

AUTO: Same as above specifications for above 40 Hz.
(The table shows the sensitivities in terms of the amplitude displayed on the CRT.)
(>min. for the HFREJ sensitivity shoes that the amplitude necessary for synchronization increases.)
FIX * : Same as above specifications for above 50 Hz.

SAFETY
LS 8105A/LS 8106A
10
SAFETY
Before connecting the instrument to a power source,
carefully read the following information, then verify that
the proper power cord is used and the proper line fuse is
installed for power source. The specified voltage is shown
on the rear panel. If the power cord is not applied for
specified voltage, there is always a certain amount of
danger from electric shock.
Line voltage
This instrument operates using ac-power input voltages
that 100/120/220/230 V at frequencies from 50 Hz to
60Hz.
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.
Voltage conversion
This oscilloscope may be operated from either a 100V to
230V, 50/60 Hz power source. Use the following
procedure to change from 100 to 230 volt operation or
vice versa.
1. Remove the fuse holder.
2. Replace fuse F1 with a fuse of appropriate value, 1
amp for 100 VAC to 120 VAC operation. 630 m amp for
220 VAC to 230 VAC operation.
3. Reinsert it for appropriate voltage range.
4. When performing the reinsertion of fuse holder for the
voltage conversion, the appropriate power cord should
be used. (See Fig. 1.)

ADJUSTMENT
To obtain the best performance, periodically calibrate the
unit. Sometimes, only one mode need be calibrated, while
at other times, all modes should be calibrated. When one
mode is calibrated, it must be noted that the other modes
may be affected. When calibrating all modes, perform the
calibration in the specified sequence.
The following calibration required an accurate measuring
instrument and an insulated adjusting flat blade
screwdriver. If they are not available, contact your dealer.
For optimum adjustment, turn the power on and warm up
the scope sufficiently (more than 30 minutes) before
starting.
Before calibrating the scope, check the power supply
voltage.
TEST EQUIPMENT REQUIRED
The following instrument or their equivalent should be
used for making adjustment.
PREPARATION FOR ADJUSTMENT
Control Settings
The control settings listed below must be used for each
adjustment procedure.
Exceptions to these settings will be noted as they occur.
After completing a adjustment, return the controls to the
following settings.

1) Move the spot to the CRT center by operating the POSI controls.
2) Short circuit CN105-1 and 3 of X73-2210 and adjust VR4 so that the
voltage between CN105-2 and GND is 100M 35.6/50M 33.8V.
3) Adjust VR306 so that the voltage between CN670-1 and GND of X74-
1640 is 70V and confirm that between 4 and GNd is 70V.

1) Move the spot to the CRT center by operating the POSI controls.
2) Adjust the spot to the best point with FOCUS on the panel and ASTIG

3) Set FOCUS on the panel to the 12:00 position and adjust VR102 to
move the spot to the best point.

CH2 INV Balance VR205

1) Adjust so that the trance does not move when CH2 INV is switched ON-
OFF.
2) Check CH2 STEP ATT BAL and VARI BAL and, if any is deviated, re-
adjust following the adjustment procedure.
V.MODE : CH2 AC-DC : GND
VOLTS : 5mV H.MODE : A
ADD POSI VR371
1) Superimpose the two displayed traces by operating CH2 POSI.
2) Switch V.MODE CH2 ON. (After this, CH1, CH2 and ADD of V.MODE
are ON.)
3) Superimpose the two displayed traces by operating CH1 POSI.
4) Adjust the trace to the center of scale.
(The CRT seems to display a single trace but it actually consists of a
superimposition of 3 traces.)
V.MODE : CH1, ADD AC-DC : GND

1) Input CH1, 1 kHz sine wave, and 16 div.
2) Adjust GAIN so that the edges of both upper and lower wave forms will
be in the same position when POSI is turned upward and downward to
a maximum extent.
3) Adjust CH2 in the same way.
4) Display only CH1 and conduct auto setting. Then adjust the POSI
center so that the bright line will be in the center.
5) Display only CH2 and conduct auto setting. Then adjust the POSI
center so that the bright line will be in the center.
6) Set the POSI knob of CH3 at 12:00, and make adjustment so that the
bright line will be in the center.
V.MODE : CH1, CH2, CH3 AC-DC : GND
VOLTS : 10mV H.MODE : A
Adjust by setting VARIABLE to the MIN (fully counterclockwise) position
with reference to the MAX (CAL) position.
* Ensure that the trace does not move when VARIABLE is switched
between MINíîMAX.

Item Adjustment
No.
ProcedureP.C.B.
26
CH2 TRIG DC
Coupling
It differs from
"LS 8105A"
VR207 Initial configuration: unnecessary
1) Enter the voltmeter mode by means of the cursor switch.
2) Turn on CH2 10mV DC GND, set the trigger source to CH2, and set the
trigger coupling to DC and make adjustment so that the measured DCV
will be within ±0.2mV.(VR207)
3) After turning off the power, turn on the power again to end the
adjustment mode.
4) "LS 8105A" is the same method as CH1, and unites DC coupling start
with AC coupling start.

CH3 TRIG DC
Coupling VR303
1) Adjust TRIG LEVEL so that the waveform starts from the scale center
line.
2) Set the trace to the scale center by operating V.POSI.
3) Input a 1kHz sine wave to CH1 and set it so that it extends by 3 div.,
above and below the scale center line. (As CH3 is fixed to DC, it may
not be triggered at this time. But it can be triggered by adjustment.)
4) Switch COUPLING to DC and adjust so that the waveform starts from
the scale center line.

VR106 Inidtial configuration: unnecessary
1) After turning off the power, turn on the power while pressing the ∞SW
of MODE to enter the adjustment mode.
2) Enter the voltmeter mode by means of the cursor switch.
3) Turn on CH1 10mV DC GND, set the trigger source to CH1, and make
adjustment so that the measured DCV will be within ±0.2mV. (VR107)
4) Input a 1 kHz sine wave to CH1, and shift it by 3 div to up and down
from the center of scale, respectively.
5) Let the starting position of the wave form coincide with the center of
scale by means of TRIG LEVEL.
6) Change COUPLING to AC, and let the wave form starting point of the
DC coupling coincide with the AC coupling starting point (VR106)
