WARNING
●In measurement with this instrument, high voltage
may be applied and high current may be supplied.
Always close the cover before measurement after
setting the DUT (Device Under Test) on the Test Fix-
ture. Also, do not open the Test Fixture cover dur-
ing measurement.
High voltage (max. 5 kV) may be applied and high current (max. 2 kA) may be supplied to the ter-
minal to which the DUT is mounted. To prevent danger, if the cover of the Test Fixture is not closed,
no voltage and current can be supplied to the terminal and no power can be applied to the DUT.
And, do not remodel the switch for power supply shutoff or do not open the cover during measure-
ment. If not, electric shock may be caused. When it is detected that the cover of the Test Fixture is
opened during measurement, the supply of voltage and current to the terminals is immediately cut
off, and the energization of the DUT is stopped. For your safety, do not open the cover during meas-
urement.
●After the measurement is completed, the meas-
urement DUT may be charged and generate heat.
Never touch the measurement DUT until you can dis-
charge it with a grounding rod, take measures
against heat, and confirm the safety.
Touching a charged or generated measurement DUT may cause electric shock or burns. Take
measures such as using gloves, antistatic measures, and leaving the instrument for a suffi-
cient period of time.
●When using anything other than the test wire
lead or small crocodile that comes with the Test
Fixture, pay attention to the withstand voltage
and allowable current.
If the measurement is performed without considering the measurement potential, cable outer insula-
tion, and GND cable outer insulation rating, it may cause a fire or malfunction. Use the specified cable
that comes with the Test Fixture according to the measurement content.
●Always use the interlock function.
Connect the interlock circuit to the INTERLOCK connector of this instrument. Also, check regularly
that the interlock function is working properly.

Chapter 1 Overview
Curve Tracer CS-8000 Series Instruction Manual 1-1
Chapter 1 Overview
The development of semiconductor technology is remarkable and diverse, and the number of equipment
such as heavy electric power (electric power), home appliances, air conditioning, and transportation that
incorporate power devices such as inverters continues to increase, and the technological progress is
remarkable. In power electronics technology, we are moving from the conventional pursuit of high effi-
ciency of electric power to the one that tries to reduce the energy density (make it compact) or that is
eco-friendly. In the transportation industry such as trains, the automobile industry, and power device
manufacturers, the development of components for eco-friendly instruments is rapidly expanding.
Inverter technology used in many electronic devices such as air conditioners, refrigerators, elevators,
trains, hybrid cars, solar power generation and wind power generation is a circuit technology that is
indispensable for energy saving. The importance of evaluating next-generation power semiconductor
devices such as SiC and GaN is increasing in order to improve the efficiency of these energy uses.
The Curve Tracer CS-8000 Series was developed by further enhancing the Curve Tracer CS-3000 Series
and CS-5000 Series in order to evaluate power semiconductor devices in the power electronics market.
1.1 Features
The CS-8000 Series is a most-advanced Curve Tracer that can handle maximum peak voltage of 5 kV /
maximum peak current of 2 kA by combining with various optional units.
You can select the Main Unit, high current unit (HC Unit) and Test Fixture CS-322 / CS-320 required for
measurement according to the application.
The Main Unit CS-8200 / CS-8500 consists of an HV unit (2 kV / 5 kV), an MV unit (common to all Main
Units) and a GATE Unit (common to all main units). The Main Unit CS-8020 consists of an MV unit
(common to all main units) and a GATE unit (common to all main units).
By combining the HC Unit CS-205 / CS-210 / CS-220, it is possible to measure with a current of 500 A /
1 kA / 2 kA.
It can be used not only for measuring the characteristics of high-voltage and high-current power devices
such as the latest IGBTs and power MOSFETs, but also for measuring the characteristics of various
semiconductors such as transistors, diodes, and LEDs. The measurement results can be saved or sent
to a PC via the standard USB port and LAN interface. The main features are shown below.
■Maximum voltage, maximum current
The Curve Tracer CS-8000 Series has a maximum supply voltage of 5 kV and a maximum
supply current of 2 A in PULSE mode.
■HC Unit option for high current
High current can be measured by connecting to the HC Unit and Test Fixture.
The maximum supply current of the HC Unit CS-220 is 2 kA in PULSE mode.
The maximum voltage at no load can be measured up to 50 V.
■Wiring for each test item can be automatically changed in the Test Fixture
According to the CONFIGURATION in the CS-8000 Series, the device and various supply power
supplies are selected, and the wiring is automatically switched internally. Therefore, the recall
function of the setup allows smooth connection switching of various measurements without
opening and closing the Test Fixture cover.

Chapter 1 Overview
1-2 Curve Tracer CS-8000 Series Instruction Manual
■In pulse measurement, sample position can be set while checking the pulse
waveform.
As for the waveform setting time of the applied pulse, the applied pulse width and data acqui-
sition timing can be set while checking the voltage waveform and current waveform, so meas-
urement can proceed with confidence.
■Handling of the DUT (Device Under Test)
The CS-8000 Series is usually used by connecting the optional Test Fixture CS-322, but an
unique Test Fixture might be required due to the size and shape of the DUT, or additional equip-
ment for measurement.
The configuration is extensible to accommodate such test environments.
When using the Test Fixture CS-322, set the DUT by one of the following three methods.
・Set the optional Patch Panel CS-520 in the Test Fixture.
Connect the Test Fixture connection terminals and the Patch Panel terminals with test wire
leads.
Connect the DUT into the socket of a compatible Test Adapter and then set the Test Adapter in
the Patch Panel. CS-500 to CS-510 are available as Test Adapters (optional).
・Without using a Patch Panel, connect the terminal of the Test Fixture and the terminal of the
DUT directly to the terminal of the Test Fixture with a test wire lead with an Crocodile clip or an
HV/HC cable.
・Manufacture a dedicated measurement panel (jig) that matches the DUT, install that panel
instead of the Patch Panel, and then connect wires directly between the measurement panels.
Efficient measurement is possible by preparing a measurement panel that can be securely con-
nected to the DUT and that can be easily attached and detached.
For Test Fixtures with the DUT set, close the cover before measuring.
■Remote Control
The CS-8000 Series supports LAN interface (10/100/1000 Base-T). Connect to an external de-
vice via the ETHERNET connector on the rear panel. For details on usage, commands, etc.,
refer to the Remote Control Manual included in the attached CD.
CAUTION !
When using a LAN interface for remote control, be sure to use a shielded LAN cable (STP) for the
