immunity test

A category of immunity test which simulates electrostatic discharge
phenomnon that a charged human body or object discherges to an electronic
product.

Contact discharge

A method of the ESD immunity testing in which the discharge tip of thedischarge gun is kept in contact with the EUT or coupling plane and thedischarge is actuated by the discharge switch of the simulator. It is an
unrealistic phenomenon in nature, but enables the test more reproducible.

Air discharge

A method of the ESD immunity testing in which the discharge tip of thedischarge gun is moved towards the EUT until the tip touches the EUT. It iscloser to natural phenomenon but has an unstable elements since it isdependet on test enviroment due to discharge in the air.

18. RADIATION LEVEL MODE
This simulator can reduce the radiation noise generated by the discharge gun.

18-1.

Radiation Noise

When the internal high-voltage relay in the discharge gun is operated by inputting the trigger switch, aspark discharge unique to the high voltage occurs at the contact point with the internal high-voltage
relay.
As this spark discharge occurs within the sealed high-voltage relay, it causes no direct danger to humanbodies. It, however, may incur radiation noise, which impacts EUT.
This simulator has been improved so that the radiation level can be lower than our previous models. If
differences of structure, radiation level and so on between this model and other models are taken into
consideration, the test result may be thought different from what it could be otherwise.
Based on the above presumption, this simulator is equipped with a special function for lower radiation
called extra mode【EXTRA】as a default setting and it can be switched to normal mode【NORMAL】easily
to make the radiation level same as our previous models.

18-2.

Differences between Radiation Level Modes

There are differences between extra mode (EXTRA) and normal mode (NORMAL), as shown below.

1 Different level of radiated noise
The radiated noise in extra mode (EXTRA) is lower.
The radiated noise in normal mode (NORMAL) is at a similar level to previous simulators.

2 Difference in the voltage waveform
There is a difference in the open voltage waveform of the discharge gun output. It can be expressedwith test conditions, as shown below.
Electrostatic discharge mode: Contact discharge mode

Impedance between the discharge tip and discharge gun GND: 2MΩ or more

IEC 61000-4-2 and ISO 10605 standards do not stipulate any open voltage waveform.
For the current waveform using the specified target, there is no difference between extra andnormal modes.
Testing in normal mode does not necessarily guarantee that test results will be identical tothose obtained from previous simulators.
Electrostatic tests are affected by the individual variability of the simulator main unit anddischarge gun.
They may also be affected by the test environment and arrangement method.

19. DISCHARGE DETECTION FUNCTION
The discharge detection function detects the actual discharge in air discharge mode and notifies the user.
To enable this function, it must be set by the utility. see 23-3. SETTING 2 - Special Function
Settings.

19-1.

Operation of Discharge Detection Function

The discharge detection function only operates in air discharge mode.
The detection operation starts, when the trigger switch is turned on and the discharge relay inside thedischarge gun is turned on.
After that, the detection operation stops, when a discharge is detected or the trigger switch is turned off.
When a discharge is detected, it operates as shown in Table 19.1 below, according to the utility setting.

The discharge detection function is used to detect spark discharges caused byelectrostatic discharges. In some cases, therefore, no discharge may be detected,
depending on the impedance of the discharge channel and the charged status of thedischarged object.
Moreover, no discharge may be detected, depending on the type of the CR unit (CRvalue) attached to the discharge gun.



If the discharge detection function does not work under the above conditions, thesensitivity of the discharge detection function can be changed.
For details of the setting method and other information, see 23-3. SETTING 2 - Special
Function Settings.

When the discharge gun TC-815 series is used, the discharge detection function is notavailable.

6220. AUTOMATIC CR UNIT & DISCHARGE CUPRECOGNITION FUNCTION
The automatic CR unit & discharge cup recognition function is used to determine the type of the CR unit
and the type of the discharge cup attached to the discharge gun as well as checking their combination.
It checks whether the combination result complies with IEC 61000-4-2 and ISO 10605, and displays theoutcome on the screen.

20-1.

Operation of Automatic Recognition Function

When the CR unit or discharge cup for thedischarge gun is replaced and the power of this
instrument is turned on, automatic recognition isenabled to determine their types.
The CR unit and the discharge cup are determined
separately. If their combination complies with astandard, the compliance standard is displayed at
the bottom of the main menu.
It automatically determines whether or not thefollowing standards are complied with:
 IEC 61000-4-2 Edition 1.2

1)

Principle of electrostatic tester
The basic circuit of an electrostatic is shown below.
① The high voltage generated in the high voltage power supply is charged in the charging capacitor
through the charging relay and charging resistance.
Pressing [START] status on this simulator② When the charging relay is turned off and the discharging relay is turned on, the high voltage(electric charge) accumulated in the charging capacitor is applied to EUT through the discharging
resistance.

Electrostatic test by IEC standards
The international Electrotechnical Commission (IEC) issued the Standards for Electrostatic
Discharge Requirements Pub. 61000-4-2, which defined tester circuits and constants, discharge
current waveforms, test voltage levels, test environments, etc. A combination of the ESS-S3011A
and discharge gun can be used for electrostatic discharge tests conforming to IEC pub. 61000-4-2.

82

24. BACKGROUND KNOWLEDGE ABOUT ELECTROSTATIC DISCHARGE TESTING

3)

Contact Discharge and Air Discharge
The electrostatic discharge can be applied either by direct contact (CONTACT) or via the air(AIR). The test procedure and electrostatic simulator operation are different in each case, as
described below. The effect on the EUT is also different.
 Contact discharge (CONTACT)The electrostatic discharge is applied by placing the discharge tip in direct contact with thecase of the EUT (if the case is painted, the paint is peeled off to allow contact).
Coupling between the internal circuits and the discharge current that flows through the caseof the EUT causes the EUT to malfunction. Because the discharge contacts the EUT directly,
this method of testing has a comparatively good level of repeatability.
The test uses a cone-shaped discharge tip that extends out from the end of the discharge gun.
After bringing the discharge tip into contact with the measurement point on the EUT, thetrigger is input to apply the specified number of discharges to the EUT at the specified timeintervals. Discharging can be paused by inputting another trigger while discharge is inprogress.
 Air discharge (AIR)In the IEC standard, this method is used in situations when contact discharge is not practical(when it is stipulated that an insulating coating is applied or the EUT case is made of an
insulator).
In this method, the discharge gun uses a discharge tip with circular shape.
Turn on the trigger with the discharge gun held away from the EUT and then as rapidly as
possible bring the discharge tip closer until it comes into contact with the EUT. After thedischarge occurs, pull the discharge tip (discharge gun) back away from the EUT and turn off
the trigger. Repeat this the specified number of times.
Also, the discharge interval setting is not applicable when using air discharge mode.

4)

Test Procedure for Electrostatic TestingElectrostatic testing must be performed under specific conditions including factors such as theground plane and coupling plane. Refer to the "IEC61000-4-2" standard published by the IEC
for details.
