    • Ideal for "Pre-compliance" preliminary conformance test of EMI official test.
    • Total test system including not only antenna, spectrum analyzer for EMI, LISN and PC software for EMI but also anechoic box.

What can be done?

  1. 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).
  2. The source of noise can be found.
    • Magnetic field measurement of PCB in EUT
      The source of the emission noise can be found by using a magnetic field probe CP-2SA of option and measuring the magnetic field on the print circuit board.

Features

  1. EMI Total Test System without Additional Equipment.
  2. As a complete and total test system including not only antenna, spectrum analyzer for EMI, LISN and PC software for EMI but also anechoic box, MR2300 is the first in the world.

    In addition, the magnetic field probe (option) is prepared as a problem solution tool.

  3. Compact and broadband antenna by our own development.
  4. Broadband antenna MAN101

    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.

  5. Small, medium and large anechoic boxes.
  6. Calibration of the entire system
  7. 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.

  8. Confirmity to regional and international standards
  9. 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

Figure:MR2300

When ①, ② or ③ in the whole system chart shown above is connected to <About magnetic field probe CP-2SA> [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.
*PC and CP-2SA are not included in the system price.

  1. Radiated emission test
  2. 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.

  3. Conducted emission test
  4. 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.

  5. Search of the source of disturbance noise 
  6. The magnetic field distribution on a print circuit board can be precisely measured by using magnetic field probe CP-2SA of option.

    As a result, it is very convenient as a debugging tool because the source of disturbance noise that exceeds the limit line can be easily found out.
