EMI Measurement System

 

With the shift to digital and mobile electronic devices with the change to high-density packaging, identifying noise sources and taking mitigating measures for EMC have become increasingly difficult. Solutions for responding to yearly revisions in standards such as increases in frequencies at the upper measurement limit and maximizing the amount of data that is collected and saved for complicated noise fluctuations are in demand.
TOYO developed the “EPX” and “ES10” software series to respond to these demands. We supply and propose EMI measurement systems that suit a variety of users.
Our refined user interface dramatically improves ease of use, satisfying beginners and experts alike. From simplified tests for electronic device EMI mitigation to final compliance tests performed in accordance with standards, our automation of EMI measurement allows you to realize a clear increase in measurement efficiency.

Lineup

1. System for Radiated Emission (30MHz-40GHz)
The system uses an antenna to receive the radiation noise of the equipment under test (EUT), obtain the data of frequency spectrograph and perform the QP measurement for the receiver, carry out countermeasure against noises and process the final certified test.
With the extension of the 1GHz-40GHz frequency range, we carry out an optimal combination among the antenna, the preamplifier, the frequency spectrograph and the receiver in order to provide our customers with best suitable test system scheme.

 

2. System for Conducted Emission/ Radiated Magnetic Field (9kHz-30MHz)
Conducted noise from the EUT is measured with equipment such as an artificial mains network and a current probe. This system is also compatible with ISN and AAN, networks for communication ports that meet CISPR 32 requirements.

 

3. System for Testing Disturbance Power (30MHz-1GHz)
The system detects the noise power of EUT by using a power absorbing clamp and measures the frequency and level of noise by using frequency spectrograph and receiver. Use an automatic slide rail device of the absorbing clamp.

 

4.System for Testing Site Attenuation
In order to measure the amount of attenuation, such system performs the semiautomatic measurement by using dipole antenna and performs the automatic measurement by using broad-band antenna. The Normalized Site Attenuation (NSA) is corresponded to the three antennas method or based on ANSIC63.4.

 

5. Test System of Site Voltage Standing Wave Ratio (SVSWR)
The system is used for the SVSWR method to perform site evaluation for GHz frequency. And the system can perform a high-reproducibility measurement through a dedicated transmission antenna positioner.

 

6. Test System for Radiated Spurious Emission
The system is used for detecting the radiated spurious emission of mobile phones, wireless LAN and other equipments and is capable of performing the actual radiation power detection and stray detection corresponding to the 3rd Generation Partnership Project (3GPP) standard and European Telecommunication Standards Institute (ETSI) standard.
