2 DESCRIPTION
Because of the modular construction of the Sonopuls 190 the description is on block diagram
level.
2.1
2.1.1
BLOCK DIAGRAM
The electronic circuit of the Sonopuls 190 is located on 2 modules:
- Application / display module (also referred to as main PC Board).
- User interface module (also referred to as keyboard)
The Ultrasound Treatment Head (UTH) is connected to the unit without using an connector
which makes it unable to disconnect the UTH by the user. The electronic circuit of the
treatment head (feedback circuit) is found on the main PC Board. The treatment heads used
with other series are equipped with a feedback and an head id. circuit inside the UTH which
makes the heads interchangeable with other units. Other units are able to provide two output
frequencies 1 and 3 Mhz, the Sonopuls 190 unit is a single frequency unit. Because the UTH
which is used with the Sonopuls 190 unit does not have this circuits inside, the UTH must be
calibrated to the unit in question. One advantage is that the treatment cable is available as a
spare part because it is a part of the electronic circuit. The calibration routine covers the
complete unit including cable and treatment head assembly.
Application module
The function of the application module is to supply the Ultra Sound (US.) drive current for the
Ultrasound Treatment Head (UTH) connected to the Sonopuls 190 unit.
The Ultra Sound drive current is an alternating current at a frequency of 1MHz and can be
either continuous or pulsed mode.
(see appendix B fig. 1)
(main PC Board)
2.1.2
The application module comprises the following circuits:
- US. micro controller circuit
- US. measuring circuits
- US. driver and output stages
- Timer circuits
- LED display
The ultrasound treatment head connected to the Sonopuls 190 unit is specially designed and
it has a permanent connection to the unit. The UTH. does not have a connector and
therefore it is not possible to disconnect it from the unit.
User interface module
The keyboard is found at the front of the Sonopuls 190 unit. The switch-matrix is decoded at
the main PC Board. The LED displays ( which are a part of the main PC Board) will give a
clear view of the treatment parameters and treatment timer.

Ultrasound Treatment Head
The Ultrasound Treatment Head (UTH) comprises the following part:
- Ultrasound crystal
The treatment head itself is not a serviceable item because the head parameters (impedance
of the crystal) are to be factory determined. The head parameters (crystal properties)
required for calibration of the unit are found on a label at the main PC Board connector side
of the treatment head cable.

The adjustment procedure for the Sonopuls 190 is carried out under the following test
conditions:
- The mains voltage must correspond with the technical specifications of the Sonopuls 190.
- The ambient temperature must be 25°C ± 5°C.
Ultrasound Unit/Treatment Head combination adjustment
After replacing the main PC Board and/or an ultrasound treatment head the Sonopuls 190
unit must be calibrated.
For calibration of the UTH. two values are required:

Treatment head constant (crystal properties) is factory determined and is found on
a label at the main PC Board connector side of the treatment head cable.
The calibration is as follows:
Output power calibration:
- Connect an Ultrasound Treatment Head to connector CN1.
- Put the UTH. into the ultrasound dummy load (see par. 3.1).
