MIL,STD-461 Tests

Why is the MIL-STD-461 Test is Necessary

Ege Test Center and MIL-STD-461 Testing

The MIL-STD-461 standard, which we test as the Ege Test Center, is required for the activities of the Ministry of Defense (DoD) and the requirements for the control of electromagnetic interference (EMI) emissions and sensitivity characteristics of electronic, electrical and electromechanical equipment and subsystems designed or supplied for use by their agents. The MIL-STD-461 standard is the basic standard for military electromagnetic compatibility testing at the device and subsystem level.

Measurement Forms;

Dissemination through conductivity (CE-Conducted Emission)
Susceptibility through conductivity (CS-Conducted Susceptibility):
Since the MIL-STD-461 is developed for use on all platforms and different platforms have different needs, all tests specified in the standard are not applied to all platforms.

For example;

Test CodeDescription
CE101Conductivity Transduction, Power Lines, 30 Hz – 10 kHz
CE102Conductivity Transduction, Power Lines, 10 kHz – 10 MHz
CE106Conductivity Transmission, Antenna Terminal, 10 kHz – 40 GHz
CS101Conductivity Throughput, Power Lines, 30 Hz to 150 kHz
CS103Sensitivity through Conductivity, Antenna Input, Intermodulation, 15 kHz – 10 GHz
CS104Sensitivity through conductivity, antenna input, suppression of unwanted signals, 30 Hz – 20 GHz
CS105Sensitivity through Conductivity, Antenna Input, Cross-Modulation, 30 Hz – 20 GHz
CS106Conductivity through Transition, Transitions, Power Lines
CS109Sensitivity through conductivity, construction current, 60 Hz – 100 kHz
CS11414 Conductivity through Cable Conductivity, Cable Injection, 10 kHz to 200 MHz
CS115Sensitivity through Conductivity, Cable Injection, Impact
CS116Sensitivity through conductivity, suppressed sinusoidal transitions, cables and power lines, 10 kHz to 100 MHz
RE101Radiation Transmission, Magnetic Field, 30 Hz – 100 kHz
RE102Radiation Transmission, Electric Field, 10 kHz – 18 GHz
RE103Radiation Transmission, Antenna Harmonic Outputs, 10 kHz – 40 GHz
RS101Fluorescence Through Radiation, Magnetic Field, 30 Hz – 100 kHz
RS103Fluorescence Through Radiation, Electric Field, 2 MHz – 40 GHz
RS105Temporality through Radiation, Temporary Electromagnetic Field

For example, the CE101 test is applied to the devices to be used in aircraft, submarine and ground forces,
but not to the devices to be used in aircraft connected to air forces. The CE102 test, on the other hand, is a test for all platforms. Although the standard on which the test is to
be applied to which platforms are defined, the conditions specified in the standard may not be met or the tests not required by the standard may be requested by the customer and the testing needs are only hard to follow from the standard. Therefore, starting from the start of the project test planning and preparation of a Test Plan document is very useful.

What is Radiated Emission test?

Important of Radiated Emission Testing

Ege Test Center and Radiated Emission Test

Radiated Emission , in other words, by means of Radiated Propagation is only one of the Electromagnetic Compatibility (EMC) tests. According to the product to be tested according to the EMC standard is determined after determining an anechoic chamber (anechoic chamber) or in the open field test area (OATS) is a test must be done. The purpose of the Radiated Emission test is to determine whether the unwanted electromagnetic frequencies of the product are below a certain level. Radiated EmissionIf the measurement results of a product being tested are below the limit values ​​specified in the relevant standard, this test is considered to have passed. If the measurements on the limit are obtained, a change in design or EMC is required on the remaining product. The studies carried out on this kind of product are R & D studies and are very important works for the producer.

What You Need to Know About Radiated Emission Test

The measured frequency range of the Radiated Emission tests usually starts at 30 MHz and can be up to 1GHz, 2GHz or 6GHz depending on the product specification and the applied standard. Measurements are made with the antennas designed for the specified frequencies and the measurement devices called the EMI Receiver. The measuring distance between the product and the antenna is usually 3 meters or 10 meters. It is also possible to change the limits according to the measuring distance. For example, the limit value of 40 dBuV / m at 3 m can be reduced to 30 dBuV / m if the measurement is done at 10 m.

The Radiated Emission test is one of the most basic tests of EMC tests, so it is a test that the product designers should be familiar with. Measures related to EMC testing of a product should start at the design stage of the product and continue during the serial production phase. Even when the product is in the end user, it should be followed.

EMC Test for Medical Devices

The Importance of Medical Devices in Our Lives

Nowadays, the medical devices used in medicine are very important. Ultrasound, magnetic resonance, dentist chair, radiological methods, such as the diseases formed in our body to be seen in the finest detail is possible to see. There are EMC tests that must be applied to medical devices used in medicine, the accuracy and construction of these tests is very important. In the case of improper application of parts, such as standard, test coverage, human health is at great risk when any problem occurs.

The Importance of CE Marking for Medical Devices

Why Pre-Compliance EMC Testing?

Electromagnetic Compatibility (EMC) testing is one of the essential requirements prior to marketing electrical products. Most of the electrical equipments need EMC testing due to some technical and legal reasons. EMC test standards are varying according to the region or country that the product will be marketed to. Product designers and manufacturers have to be aware of these standards and shall market their products according these regional or international standards. Prior to full compliance EMC testing, pre-compliance EMC testing plays an essential role. By performing some of EMC tests in their own facilities, product designers and manufacturers will ensure that their products fulfill EMC testing standards partially. This will give them a great advantage prior to full compliance EMC testing or certification of the products by third party testing laboratories.

In order to set up a pre-compliance EMC testing laboratory, there are many solutions on the market. These solutions depend on the features of the Equipment Under Test (EUT). By listing the EMC test standards and specific tests according the product features, EMC testing chambers or equipments can be selected. These pre-compliance EMC test equipments will not cost as much as accredited EMC testing laboratories since some deviations can be ignored due to the tests are pre-compliance.

Automotive EMC Test: CISPR 25, ISO 11452-2 and Equivalent Standards

Room Testing for EMC Standards and Automotive Components

Automotive standards for electromagnetic compatibility (EMC) are mainly developed by CISPR, ISO and SAE. CISPR and ISO are organizations that develop and maintain international standards of use. SAE develops and maintains standards for use primarily in North America. In the past, the SAE has developed several EMC standards, which were eventually submitted to CISPR and ISO for consideration as an international standard. When SAE standards become international standards, the equivalent SAE standard is withdrawn as a full standard and is reserved for use in documenting differences in international standards.

Each vehicle manufacturer has internal standards that determine the levels and tests that the components used in their vehicle must meet. As with government standards, these documents often refer to CISPR and ISO documents, which differ in scope or test levels. In the past, a US-based vehicle manufacturer has applied SAE documents to corporate standards. Most of today

USA-based vehicle manufacturers worldwide market. For this reason, they refer to CISPR and ISO standards in their internal standards, and this applies to other established and developing manufacturers.

CISPR 25 and CISPR 12

The CISPR 25 is typically not used for regulatory purposes, but is commonly used by vehicle manufacturers to ensure good performance of vehicle-mounted receivers. If the radio installed in the vehicle, boat or other device does not perform reliably, consumer satisfaction and consequently product sales may be damaged.

Both CISPR 12 and CISPR 25 relate to vehicles operating on internal combustion engines (land-based vehicles), boats working with internal combustion engines (vehicles running on the water surface), and devices (but not necessarily) that work with internal combustion engines. for the transport of people). This latest category includes compressors, chainsaws, garden equipment and so on. It contains. CISPR 12 applies to all of these devices, as this may affect the performance of nearby (external) receivers. However, CISPR 25 should only be considered for products containing built-in receivers. For example, a chain saw with an internal combustion engine (but without built-in receivers) must meet the requirements of CISPR 12, but CISPR 25 does not use any built-in receiver for this saw.

CISPR 12 emitted emission measurements are made at 3-meter or 10-meter test distances. Measurements are normally made in an outdoor test area (OTS) or ALSE in an absorbent coated shield if the ALSE can be correlated with an OTS. Measurements can also be made for boats for water. The correlation of ALSE with an OTS has been a topic of discussion within the group of experts responsible for maintaining CISPR 12 over the past few years. The specification does not currently provide a method for obtaining this correlation. A working group is tasked with developing a method for associating ALSE with OTS; However, this may take more than a few years and we are expecting CISPR 12 7 then   published in th Version.

EMC Directive in non-EU States, countries & territories

European Union published a guide regarding Electromagnetic Compatibility (EMC) directive: Guide for the EMCD (Directive 2014/30/EU)

As this EMC Directive Guide mentions, the geographical application is described in Chapter 2.8 “geographical application” of the Blue Guide. The EMCD also applies in the EEA-EFTA States (Liechtenstein, Iceland, and Norway) and Turkey. Therefore, when the terms “European Union”, “Union”, “territory” or ‘Member States’ are used in this Guide, they apply to the EEA-EFTA States (Liechtenstein, Iceland, and Norway) and Turkey.

Ege Test Center helps designers, manufacturers, engineers, importers, exporters, researchers, universites and all other parties need EMC testing according to EMC Directive. You can ask any question regarding EMC Directive or send your request by using our Online Application form:

Detectus RSE Series

Visual Noise  Detection

The patented EMC scanner measures emissions from PCBs, components, cables and products. 

It has features such as the XYZ robot, a spectrum analyzer with near-field probe and communication with a standard PC or spectrum analyzer with special software and GPIB card. During measurement, the near-field probe is carried by the robot to a grid of measurement points on the test object. The position of the probe and the value of the emission intensity at each measurement point are stored in the computer. After measurement, the results can be documented in different types of reports.

Purpose comparative measurements

EMC Scanner is one of the most useful features of the system, allowing you to make really objective comparative measurements.

Below you can see an example of comparative measurements. Six measurements show the same test object and the same frequency. The difference is the value of the dissociation capacitor of an IC.


The MultiScan measurement allows you to create area graphics from any frequency within the measured broadband range. This powerful feature is a great improvement and gives a tremendous amount of information. When the right of the screen is viewed to the right of the screen, the main part of the screen shows the area graph of the frequency selected in the upper left chart.

The upper left chart shows the accumulated trace (maximum retention spectrum of all measurement points).

The upper right chart shows the broadband spectrum from a user selectable point on the area graph.

Import 3D surface models

You can now import 3D surface models in STL file format and create the following measurement points from a fixed distance. The 3D surface models can easily be aligned to the measurement using the 3-point alignment feature.

High Resolution Heat Screening

The scanner system also includes a Heat Scanner feature.

The scanner is a high-resolution measurement system for anyone who wants to accurately and accurately measure temperature. Measurements are presented graphically as two- or three-dimensional images.

Some of the main tests in EMC tests

Some of the main tests in EMC tests

  • Transmission emission
  • Electric field, radiated emission
  • Harmonic and flicker

Transmission by conduction or conductivity diffusion tests are carried out to determine the levels of electromagnetic pollution emitted by the transmission to the telecommunication or power grid to which an electrical or electronic device is connected. In this test, the voltage and current values ​​of the electrical or electronic equipment or system are measured. Voltage values ​​are measured by LISN (Line Impedance Stabilization Network) and current values ​​are measured by current probe.

The electrical appliance generates electromagnetic energy while an electronic device is operating, and a certain amount thereof is directed to the power cord of the device. In order to limit the amount of interference the device can return to, it is necessary to measure these emissions in laboratories. This value is usually between 150 kHz and 30 MHz. International standards generally apply this value. However, this frequency range may be higher or lower for certain standards. These measurements have been made to ensure that the power supply remains relatively clean and will not affect other devices in the vicinity.

Electromagnetic İnterference Emission Measurements

In summary, a device carries out electromagnetic radiation via conductivity through lines such as energy, data and telecommunications. With the tests performed, the level of this diffusion is determined and compared with the limits in certain standards.

Mainly electric field, radiation emission emission measurements (electromagnetic interference emission measurements) are as follows:

  • Measurement of electromagnetic wave radiation (radiated magnetic field emission)
  • Measurement of interference wave voltage
  • Power disturbance
  • Measurement of smooth non-continuous brittle interference waves
  • Measurement of low frequency network interference waves

Many electromagnetic compatibility (EMC) tests are carried out in authorized laboratories. Within the scope of EMC tests, our organization carries out the operation emission tests in accordance with the relevant legal regulations, standards and test methods published by domestic and foreign organizations.
