Conducted EMI Test System MR2150

Pre-compliance test system for conducted EMI.
The development cost can be significantly reduced by debugging and evaluating EUT using this system before testing in the formal EMC site.


Pre-compliance test system with superior cost performance

Operating stability and usability of this system are fully confirmed because all of components consisting of spectrum/signal analyzer, LISN and PC software have been developed by ourselves. Additionally, each price of those pieces is very reasonable. EMI test environment with superior cost performance is offered.

Spectrum/signal analyzer

Spectrum/signal analyzer can be selected according on budgets and performance / function.

Handheld Signal Analyzer MSA538E

This is a model in which EMI measurement function is added to MSA538.
Measurement frequency : 20kHz to 3.3GHz

Handheld Signal Analyzer MSA558E

This is a model in which EMI measurement function is added to MSA558.
Measurement frequency : 20kHz to 8.5GHz

Handheld Spectrum Analyzer MSA438E

This is a model in which EMI measurement function is added to MSA438.
Measurement frequency : 50kHz to 3.3GHz

High efficiency EMI test by rich software functions

PC software for EMI can correct insertion loss of LISN and cable.

Also, in the auto-sequence mode, PK(peak) over specified level is picked up in wide band and then QP(quasi peak) and AV(average) of chosen spectra are precisely measured in narrow band.

Therefore, the mesuring time is greatly shortened.

The most inexpensive LISN with good portability

Our LISN is the most inexpensive although it is equipped with a built-in transient limiter and is more portable, compact and lightweight than others.

Good portability of the LISN and MSA series provides better EMI test environment in a limited space.

Line Impedance Stabilization Network(LISN) MPW201B

A test environment can be easily constructed in a limited space.
LISN is necessary to perform stably and reproducible disturbance noise measurement.
The impedance of the power source observed from EUT side is made constant by inserting LISN in the power supply line.

Test example

EMI test example of a sample EUT(switching power supply)

The test results of MR2150(MSA558E, MPW201B) in a non-shielded laboratory and a compliance system at a formal EMC site are shown below.

The differences of QP and AV at the noise peak between the two systems are only within ±3 dB or ±4 dB as shown in figures.

Therefore, finding the source of noise and solving the problems using MR2150 before formal test will reduce the total EMI test cost.
