    EMC test system Pre-compliance EMI test system MR2300download

    • 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 3GHz by using an anechoic box and a broadband antenna.
    • 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-2S 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.

    Any other additional equipment is not needed at all.

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

    The antenna, whose dimensions are as small as 578(W)×332(H)×500(D)mm (MAN101, excluding ground plate) and bandwidth is as broad as 30MHz to 3GHz, was developed by ourselves.

    The size of anechoic box also became small by miniaturizing the antenna.

  5. Small and large anechoic boxes.
  6. only reads the measurement result on the PC screen.
  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 MSA338E 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概要

When ①,② or ③ in the whole system chart shown above is connected to <About magnetic field probe CP-2S> [RF INPUT] of Spectrum analyzer MSA338E for EMI, the radiated emission test, the conducted emission test or debugging to remove the source of disturbance noise respectively can be performed.

  1. Radiated emission test
  2. By connecting anechoic box MY5310/5410 and MSA338E with an accessory SMA(P)/N(P) coaxial cable, the radiated emission test is done within 30MHz to 3GHz.

    After receiving the disturbance noise that EUT (Equipment under test) radiates in the air with broadband antenna MAN101/102, it is input to MSA338E. The antenna gain of MAN101/102 is corrected and the electric field strength (dBμV/m) is calculated in MSA338E.

    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 RS-232C 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(MPW201) and then connecting to MSA338E with SMA(P)/N(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 MSA338E through LISN. The attenuation of LISN is corrected and the noise is converted into the unit of dBμV in MSA338E.

    The data is displayed with the limit line by the EMI standard on the screen of a personal computer after forwarded there through the RS-232C 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-2S 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.
