What is MR2300 ?
Generally or from our experience, it is said that the number or the solution time of the problems concerning EMI is 5 to 10 times larger than EMS. In short, passing EMI test means that 80 to 90 percents of EMC test are completed. Therefore, MR 2300 specializes in the EMI test.
What can be done?
Two kinds of EMI tests can be carried out.
- Radiated emission test
This test can be performed in the frequency range 30MHz to 1GHz by using an anechoic box and a broadband antenna.
※option ： It corresponds to 1GHz or more as an option. - Conducted emission test
This test can be performed in the frequency range 150kHz to 30MHz by using LISN (Line Impedance Stabilization Network).
The source of noise can be found.
- Conducted disturbance noise measurements
Using the MMP500 magnetic field probe allows for a straightforward measurement of conducted interference noise on power lines. Additionally, its strong directional capabilities enable the identification of noise sources, akin to typical magnetic field probes.
Features
MR2300 is an integration system that concentrates our spectrum analyzer technology, anechoic box technology and antenna technology.
Affordable EMI total testing system
Everything from an anechoic box, antenna, spectrum analyser for EMI, low-noise amplifier, LISN and PC software can be built in-house and is reasonably priced.
In addition, a magnetic field probe (optional) is available as a problem-solving tool.
Compact and broadband antenna by our own development
The antenna, whose dimensions are as small as 578(W)×401(H)×250(D)mm (MAN101, excluding ground plate) and bandwidth is as broad as 30MHz to 1GHz, was developed by ourselves.
The size of anechoic box also became small by miniaturizing the antenna.
Small, medium and large anechoic boxes.
Electromagnetic Anechoic Box /Shield Box Large Size MY5310
The most suitable anechoic box for EMI test. For small EUT and equipped with a turntable of 220mm in diameter / 10kg in load.
Electromagnetic Anechoic Box /Shield Box Large Size MY5310S
It is easy to carry with a small elevator and to install in the narrow space because divided into two.
Electromagnetic Anechoic Box /Shield Box Large Size MY5310SU
Separate and assembled type that can be carried in by personnel elevators and installed in small spaces.
Ferrite radio wave absorber is used, making it ideal for EMI testing. A turntable with a diameter of 500mm and a load capacity of 50kg is standard equipment for large EUTs.
Electromagnetic Anechoic Box /Shield Box Large Size MY5410
The most suitable anechoic box for EMI test. For large EUT and equipped with a turntable of 756mm in diameter / 100kg in load.
Calibration of the entire system
The calibration as the whole system like corrections of the antenna gain, attenuation of LISN and conversion into 3 meters in measurement distance is performed in Spectrum analyzer and PC software.
The user only reads the measurement result on the PC screen as it is.
Confirmity to regional and international standards
MR2300 is based on CISPR11(classA/B,group1), CISPR22(classA/B), EN55011(classA/B,group1), EN55022(classA/B), VCCI(classA/B) and FCC part15 subpartB(classA/B).
Overview
When ①,② or ③ in the whole system chart shown above is connected to [RF INPUT] of Spectrum analyzer MSA438E/538E/558E for EMI, the radiated emission test, the conducted emission test or debugging to remove the source of disturbance noise respectively can be performed.
Connection of ①-Radiated emission test
By connecting anechoic box MY5310/S/SU・5410 and MSA438E / 538E / 558E with an accessory N(P-P) coaxial cable, the radiated emission test is done within 30MHz to 1GHz.
After receiving the disturbance noise that EUT (Equipment under test) radiates in the air with broadband antenna MAN101/102, it is input to MSA438E / 538E / 558E. The antenna gain of MAN101/102 is corrected and the electric field strength (dBμV/m) is calculated in MSA438E / 538E / 558E. The calculation result is displayed with the limit line by the EMI standard on the screen of a personal computer after forwarded there through the USB cable MI400 communication and converted into 3 meters in measurement distance.
Connection of ②-Conducted emission test
By inserting an accessory N(J)/BNC(P) coaxial adaptor in the [RF OUT] terminal of LISN(MPW201B) and then connecting to MSA438E / 538E / 558E with N(P-P) coaxial cable, the conducted emission test is done within 150kHz to 30MHz.
The disturbance noise that EUT discharges into the power supply line is input to MSA438E/538E/558E through LISN. The attenuation of LISN is corrected and the noise is converted into the unit of dBμV in MSA438E/538E/558E. The data is displayed with the limit line by the EMI standard on the screen of a personal computer after forwarded there through the USB cable MI400 communication.
Connection of ③-Conducted disturbance noise measurements.
Using the MMP500 magnetic field probe allows for a straightforward measurement of conducted interference noise on power lines. Additionally, its strong directional capabilities enable the identification of noise sources, akin to typical magnetic field probes.
Power Line Noise Monitoring Equipment
Taking advantage of the characteristics of our magnetic field probes, which allow non-contact electrical measurement, the monitoring equipment combines a spectrum analyzer and logging software to monitor the noise of various secondary power supply lines.
