Care to be Taken in the Field
1)
Check for trouble symptoms.
2)
Check for connection to optional devices and other peripheral devices.
3)
Record the preset data to a floppy disk.
When record in a lump the internal data such as the preset data, patient data, image data and
others, record them to an MO disk.
After working, restore the equipment according to the above mentioned contents of memory
4)
if necessary.
5)
2-9
After completion of work, put back the peripheral devices to the original condition.
Precaution for Monitor repairing
1)
Subjecting the unit to strong shocks may result in damage to the CRT or malfunction,
therefore care must be taken when transporting or installing the unit.
*DANGER
High voltages are present inside the display chassis.
Only experienced
technicians should touch internal parts.
DANGER
The electric charge has remained in CRT after the power switch is turned off.
A
Because the high voltage is usually used for CRT. So make the electric
charge escape with a g r o g stick which is connecVd to the ground of the
chassis and through the resistance for high voltage (Approx. IMQ) before
removing the anode cap.
Some electric charge remains in CRT after escaping with a grounding stick.
Do not touch the metallic part of anode cap with bare hands, when detaching
the anode cap directly.
2)
CRT with the defleding yoke is already adjusted to the best condition. Do not touch the
deflecting yoke and the magnet of the neck part.
3)
Be sure to detach the metallic goods such as a wrist watch fTom your body before doing the
repair work.
To prevent the secondary damage and the electrical shock, the matters above should be taken
into carefut consideration.

Handling of S.M.D. PCBs
It is an Aloka's policy that neither repair nor modification of PCBs used for S.M.D. is made in
the field as a rule because of the following reasons:

Do not give excessively large shocksto the PCB,
When replacing the ROM (Read Only Memory) on the PCB, attempting to force the ROM into
its socket would cause the PCB to he subjected to an undue force, and the following faults may :
1)
Damage to PCB intermediate-layer patterns,
2)
Peeling of chip devices (resistor, capacitor, diode, etc.)
3)
Damage to a junction between electrode and internal element of chip devices,
4)
Peeling of pattems (especially those for mounting the parts) together with chip devices since
those pattems are rather fragile compared with PCBs used before now, and
5)

When handling a PCB, avoid touching the IC and connector pins on the I
Damage to parts on the reverse side in the case of PCBs of both-side mounting type.
Also, a PCB mounted improperly or a warped PCB mounted as it is may cause the chip devices
to come off and the fine patterns to be cut.
Additionally, reuse of chip devices (including resistors, capacitors, diodes, etc.) is strictly
inhibited because of the following reason:
Since the chip devices are lacking in iead wires, such
as those found in the traditional component parts, beat given to the PCB will be directly
conducted to the inside of chip devices. As a result, a thermal stress will occur due to a
difference in thermal expansion coefficient between each chip device and PCB, giving rise of the
possibility of crack. inside of or on the surface of chip devices or the possibility of thermal
breaking (internal burning).

Control of System
CPU
The CPU controls entire operation of this system that is a generic PC and it also controls HDD
and FDD.
The HDD contains:
The programs of this PC.
The programs for other peripheral processors.
m a t is transferred to the flashmemories of each PCB when the certain command is invoked)
The focus data of each probe that is for Tx and Rx circuitry.
The parameter data for scan converter unit that contains the data of each probe.
The PRESET data.
The CPU also transfers the data that is for specific probe to Tx/Rx andlor DIU units from the
HDD in accordance with a necessity while the system is running.
By utilizing the floppy disk drive, the system reads the up-grading data into HDD, makes a
backup of the preset data and maintenance backup.
Main Panel: L-KEY-81
Main Panel reads the information of operation that is made on switches, encoders and keyboard
into the system.. It communicates with the CCPU by means of serial (RS-232C) and PSI2 methods.
Peripheral MPU
There are micro processors other than the CPU mentioned above, on the CMB PCB and the Tx &
Rx Control PCB.
The program for those MF'U is also stored UI the flash memory on each CMB and Tx& Rx
Control PCB and it will he restored by the CPU when the system is up-graded.
Address !Data bus
In order to control the system, there are addressidata buses as below.
PC1 BUS:
It connects the CPU PCB and tbe DIU unit that is used exclusively for it. The
CPU transfers the data from HDD to DIU and TxRx units. (The CPU can access
to all registers that are on the Local bwWC bus/Front End bus via PC1 bus)
Local BUS:
This is the addressidata bus in the Digital Imaging unit.
USC BUS:
Ultrasound Control BUS. This is the addressldata bus in the Tx/Rx unit.
Front End Bus:
Tbis is the addressidata bus in the Front End part of the TxiRx unit.
MN2-2006 Rev.0
SECTlON 4 Principle of System Operation
There are bus bridges between PC1 BUS and LOCAL BUS, LOCAL BUS.and USC BUS. It is
open when the CPU accesses to USC bus andor Front End bus but closed for other time in order
to avoid the noise from control part leaking into the TxRx unit.
Probe data
Focus data for transmission:
The transmission focus data consists of amount of delays for each probe that is stored in the HDD
as special files and it is transferred to the flash ROM on the Trig. flT PCB. The system compares
the revision of data that is stored in the HDD and the flash ROM when it starts up and reload it to
the flash ROM if the system fmd a discrepancy between them (After up-grading, for example).
Thus, once the system transferred the data to the flash ROM, it nonnally uses the data from the
flash ROM and the data transfer from the HDD doesn't take place when yon change the setting on
the operation panel (Change the display mode and/or preset, for example).
Focus data for reception:
The source data of reception focus and the parameter data for each probe is stored on the KDD
** However, calculated focus data is not stored on the HDD
Normally, the system calculates the focus data from the source and then transfers it to the DBF
(Rx Beam former). The capacity of the memory on the DBF is not large enough to store complete
data of one probe, so the system transfers only the necessary data in accordance with the display
mode, magnification and focus points. The image responds immediately if the focus data is
already in the DBF when you operate the panel but if there isn't, the response will he delayed
about I
- 2 seconds.
When you connect a new probe at the first time, it would take maximum 5 seconds or so, for
calculating and transferring the focus data.

TxiRx module,
Digital Beam Fomer module, and

Tx Rx module :
This module transmits the ultrasound for electronic probes based on the control signals from Trig.
ITF and the transmission trigger signals (Delayed Triggers).
Front End PCB has two connectors for electronic probes @lectronic Linear / Convex / Phased
Array) and HVS (High Voltage Switch) circuitry for selecting the channel of crystals that are driven
simultaneously from the crystal array in the case of linear andlor convex probe. KVS circuitry is
controlled by Trig. ITF PCB.
The reception signal is amplified by PRE AMP and passed to Rx Beam Former via Channel
Reduction (C-R) circuitry and TGC amplifier. C-R is controlled by Trig. ITF PCB.
Digital Beam Former :
The reception signal (analog) passed from Variable Gain AMP is converted to digital signal. Then
the signal for each channel is delayed in accordance with the Rx focus data and added into an
ultrasound beam.
OThe delay is processed digitally as a readout from FIFO memory is delayed by processing
clock etc., that makes it possible to have accurate delays continuously. pynamic reception

It also has the functionality that it adjusts the weighting of each reception signal
continuously that makes the Rx beam sharper.
OSinee it is digital signal, it can be processed in parallel by time sharing and then it realizes
higher frame rate.
OIt implements Rx Beam former PCB with 16 ch circuitry as the Delay &Adder.
OThis system does not have the trouble that shows brightness difference in every lcm depth
caused by one of the Rx focus boards (Delay and Adder circuit), like SSD-650, 1200, and

Rx Pixel Focusing
(Rx continuos dynamic focusing)
Depth
For B/W US image, delayed and added Rx data passes through Pre process circuit (It is the same
as Main Amp in conventional machine), where it selects the frequency that applies to the processing
in accordance with the depth, applies LOG compression, Detector, AGC, FTC and COXTRAST etc.
(There are two identical circuitry for BNV' parallel processing.)
Then BNV' data is transferred to DIU (Digital Imaging Unit) an US line by line via USD BUS
(Ultrasonic Line Data Bus).
The delayed and added Rx data is also transferred to Flow/Doppler module for the frequency
analysis of PW Doppler and the Color Flow calculation.
Tx & Rx part also has the following circuitry.
Tx Trigger generator for the electronic probes.
The generator of control signal for Rx signal, such as Pre STC and STC signal.
Timing/Control signal generator for Tx/Rx unit.

FlowiDoppler module executes the frequency analysis for PW Doppler and Color Flow calculation.
For PW Doppler, the Rx signal from Rx Beam Former goes through Quadrature detector and FFT
frequency analysis and then transferred to DIU via USD Bus.
For Color Flow calculation, the Rx signal from Rx Beam Former is processed as the same manner
as PW Doppler that it goes through Quadrature detector and then the Rx (line) signals are stored into
Memory Block (Number of the lines depend on the Color Average setting). The data that is read out
from Memory block passes through tbe filter, which cuts out the wall motion and then the unit
extracts the velocity information that is processed by auto-correlating the data with the one from the
same depth of previous Rx line, and the intensity information of the Doppler that is processed by
auto-correlating the same signals, then it calculates the Velocity, Variance, and Power data from those
extracted information. The calculated data goes through the clutter rejection and the spatial filter
circuitry, then transferred to DIU via USD Bus (Wlich is assigned for color data).

4-5-3 Rx Beam Former
RX Beam Former is Digital Beam Former with 16 channelshoard. By cascade connection of several
boards, it configures the Digital Beam Former that supports various numbers of channels. Also by
setting different delay to every transmission beam by timesharing, it can receive multi-directional
beams simultaneously.
This PCB consists of the 16 channel phased adder and the Controller that controls the adder. Echo
Data of each channel is added sequentially by the pipeline adder with daisy chain configuration and
sent to the next board.
Block 0-3, ch 0- 15:
A.A Filter:
A.A Filter is to clear the aliasing caused by the Ai?) sampling.
A/D:
AID is the 12 bit AD converter. Sampling clock varies depend on the center
frequency of transmission. (When the center frequency of transmission (B) is
2.1 - 3.75MHz, the sampling clock is 8fD and when it's 5.0 - 10 MHz, the
sampling clock is 4fD.)
Delay & Adder:
It is ASIC and its internal configuration is as shown below. By the digital delay
circuitry, it can vary the delay time for the reception focus continuously,

Digital Filter:
Digital Filter consists of the Low Pass Filter (Band-limit the data after oversampling at 8fU to drop the data rate to 4fU) and Band Pass Filter (Cut DC
component).
SFIFO (Short FIFO Memory):
SFIFO is FIFO memory that compensates the delay in the depth direction. By
delaying the readout, it can delay by n times of sample clock. It outputs 4
sequential data simultaneously to the interpolation circuitry by shift-register.

Pipeline Adder:
Pipeline Adder adds the channel data sequentially by adding the adjoining
channel and sending out the processed data to the next channel.
Control Circuit:
Phased addition by DBF requires large amount of focus data. Focus data is divided into the
static focus data (Data that depends on probe and scan mode) and the dynamic focus data (Data
that has to be set beam by beam). Static focus data is set directly to the hardware register by the
host before releasing the freeze status. Dynamic focus data that required for next beam is
implemented by the DM.4 transfer (in accordance with Beam Timing signal) from Focus Data
memory to ASIC while the previous beam is still being received. It is done for each beam.

DMA BUS is the 16 hivbi-directional internal bus used for DMA aansfer when the focus data
is set at DBF.
Bus Interface:
It interfaces between DM4 BUS and MPU Bus OjSC Bus).

Board ID:
Each PCB slot on the Motherboard has hoard numbers so that each DBF board is able to know
the channels to process.
DMA Controi:
Focus data given to each phased adder is transferred beam by beam from Focus Data Memory
by DMA. DMA controller controls this by commands from the host and timing signals.
Focus Data Memory:
Focus Data memory keeps the dynamic focus data that sets channel for each beam for up to 3
probes.

Introduction
This trouble shooting makes integral part of the Senice Manual. And it bas been prepared for
the persistent purpose of providing for repairing guidelmes.
What bas been described herein, moreover, is subject to the prerequisite for a repair to be made
by replacing a PCB.
6-2
Precautions
To prevent a new problem (secondary disaster) from taking place in the process of trouble
shooting as described herein, every engineer concerned should duly take the following
precautions:
Never remove any part &om the electric system, including PCB, probe, cable, etc., before
powering off the equipment.
Do not proceed to a disassembly of equipment without observing the established
disassembly procedure. Be careful enough for wrongly disassembling the equipment would
damage or break it down.
To make certain of a voltage andlor a signal waveform, it is necessary to thoroughly know
the specification and handling procedure relating to a measuring instrument employed.
To ground a measuring instrument probe or the like, it is naturally necessary to know where
a signal to determine is grounded. Before using the instrument, moreover, make certain for
which the grounding terminal is intended, analog, digital, alternating current, direct current,
high voltage or low voltage.
.------------------------------

SECTION 6 Trouble shooting
6-4-6 Backup the preset data
On the SSD-3500, all the preset data including the measuring function (obstetrical table) can be
backed up and reinstalled.
There are the following two methods of backing up such data: saving the data from the preset
control available for the user and saving it from the maintenance menu for use by the service
personnel only.
The backup data is saved on the floppy disk &rough the floppy disk drive installed in the
equipment. Therefore, it is necessary to prepare a f o m t t e d floppy disk.
The capacity of backup data from the maintenance menu becomes big, because this function
saves all internal data in one lump package. Therefore, it is necessary to prepare a formatted MO
disk and MO disk drive. A floppy disk and an MO disk should be prepared by each of you when
necessary.
: o REFERENCE o The floppy disk is the 3.5-inch, 2HD and 1.44MBDOS-formatted disk The MO :
disk is 3.5-inch, DOS-formatted disk. The equipment itself has no formatting

I
I
I
I
I
unnecessary data is contained in the backup data, do not back up the preset data. I
I
If you reinstall such data by mistake, the failure may recur or a new failure may

6-4-10 How to handle start-up failure andlor locking up
Ifthe machine fails to start up or crashes even after it sta.rted, "Checklist Map" (Chapter 6-5)
would not be applicable. In that case, follow the instruction below for repair.
1)
Checking the power supply output
Fist of all, cbeck the output voltage of the power supply unit.
This system has a CPU that controls the entire system and three other CPU that are
controlling peripheral circuitry. Iftbe power supply unit didn't provide +3.3V, +5V andlor
+12V to these CPU or HDD, or somethmg wrong with the power supply unit, would cause a
trouble that affect entire system.
However, a trouble could ocnv even the power supply unit is OK because of possible
broken wire or the faulty power regulator/distributor circuitry at peripheral PCB.
CPU are mounted on the PCB below.

Trouble caused by backed up data
back-up data is stored on the HDD and if it corrupted, it would cause trouble like start up
failure.
In that case, reset the back-up data refening the chapter 6-4-8, "How to reset the back-up
data" and then, cbeck the operation of the machine.

Trouble related to data buses
It is quite difftcult to find a cause of trouble if the signal on data bus would have problem.
If the system didn't start up or crashed during an operation, refer the following description
to proceed the repair work. However, it is recommended that you should contact with the
Technical Support at earlier stage.

6-4-12 LED on PCB
Some PCB have LED on them and those LED indicate the status of PCB. You could estimate the
defective one by means of checking those LED. There are two kinds of LED that indicates the
status of circuitry independently and the other one indicates the status that is changing depend on
the relation among several PCB. Thus the indication of failure doesn't necessarily mean that the
PCB, which has this LED is defective. Following describes the location and the indication of the
LED.

Interference Noise
In the case of sudden appearance of noise and it is suspected that would be coming from outside of
the machine, try to change the setup location of the machine andlor change the line of the mains.
Refer to following points when you inspect the environment for the machine:
1)
Is there any equipment such as X-ray apparatus that would induce power fluctuation or noise
around the area?
2)
Is there any device such as computer nearby that would cause the noise?
3)
Is there any broadcasting facility such as radio station nearby?
4)
Is there any elevated cable that provides high voltage electricity nearby?
5)
Does it affect the noise level when you turn off the light or take the probe to the device?
6 ) Would the optional devices such as VTR and/or physio unit be causing the noise?
7) Does it improve if you replace the grounding wire with the thicker and shorter one? In this
case, you need to make sure that the grounding of the building is correctly set.
8)
Check the mains of the building whether the voltage is stable or has noise in it or not.
The countermeasure is different between the noise caused inside of the machine and it is from
outside. If you don't have sufficient knowledge about noise problem, contact Technical Support
after checking the following points:
1)
Does the noise occur in particular operation, mode or probe, during the normal use?
2)
Please check the voltage ofpower supply unit such as -I-3.3V, i5V, rt 12V and f15V and
ripple.
3)
Does the noise increaseldecrease when you hold the probe?
4)
Does the noise increaseidemeasewhen you change the direction of the probe?
5)
In which direction does the noise (Or line) move on the US image (Or on entire screen)? Is it
regular movement or irregular movement?

ProbeIScanner
This system can connect electric probe. Therefore, it is important to check if the probe causes the
failure or not first.
Electronic Probe
Check with other probeidevice:
Check the machine with another probe that is the same model of faulty one if it is available.
Also, if you have the same system available, check the probe that is causing the failure with
this machine whether the same trouble occurs or not.
Coin Check For electric Linear and Convex probe)
Set the machine in B Mode and put a thii metal pin such as lead wire of a resister on the
surface of the probe and move it slowly fiom one end to the other, and observe the ultrasound
image on TV monitor. If you find any of the description below during this procedure, the
probe would be faulty.
There is one echo gap.
If the probe is OK, there is a failure in between HVS (High Voltage Switch) circuitry, the
probe selector and probe. It also might be a contact failure on the probe connector.
............................................. C1
There are several echo gaps at regular interval.
If the probe is OK, it is a failure related to the T x k signal.
............................................. C1M32/C4/C5/C6
The same echo appears more than two at the same time.
It is a failure related to the signal lines that correspond to the probe transducers one-on-one, or
a failure in HVS circuit.
............................................. c2/c4/c5
Echo is missing in certain area.
If the probe is OK, it is a failure in Beam Former, HVS Control Circuit, or somewhere
between the probe selector and the probe.

Probe Code
"Probe Code" is assigned individuallyfor every probe to let the system recognize the type of probe.
"Probe Code" is also used to determine if it is connectable or not and to read the data unique to the
probe saved in the parameter memory. Probe Code is set depending on the pin arrangement in the
probe connector.
Ifthere is any pin bent or broken, it is not only failed to recognize Probe Code but it might be

Cautions for repairing TV monitor
It is not applicable to repair PC-1550 by means of replacing PCB but to replace the assembly. So
replace the assembly when you judged that a monitor is broken.
It would be a cause of damage on CRT or other trouble if you apply too much shock or vibration on
TV monitor. Be careful when you instalVdisassemble a monitor.

to the frame ground at the other end, especially, when you need take off the Anode
Cap for example.
Do not touch the metal part with bare hand because there could the electric charge still
remain in some cases even after discharge.
1)
Make sure to take off the metallic objects such as a watch before you start working.
2)
Keep the above cautions to protect the safety of worker and prevent the secondary accident.
3)
Setup location should be somewhere airy as much as possible, and avoid blocking off the
ventilating hole or placing the device close to the object that generates beat.
4)
Do not place the machine that would expose direct sunshine or too bright place. It might cause
the temperature increase or bothering the view of the screen.
5)
Do not use the monitor close to the objects with emitting magnetic force l i e transformer,
motor, or power lines. They might cause mottled color or wohblmg screen.

6 ) Handle with care during transportation and installation. Strong impact or vibration might
damage CRT or cause troubles.
7)
Make sure to turn off the power and then pulling out the power cable before replacing the fuse.
8)
Be careful not to repeat ON-OR: of Power Switch of the monitor unnecessarily. It might
cause "spot" or malfunctions of the monitor.
