The Level correction of MAT800/810 corresponding to several input frequency
Fig.1:Attenuation of MAT800/810 corresponding to 16-frequency range. The attenuation level of MAT800/810 has some frequency response that is higher at minimum frequency “ƒ0” and maximum frequency “ƒ15” and lower at […]

Date comparison between MR2300/MY5410 system and a formal EMI site
Summary MR2300/MY5410 system was developed for a precompliance EMI test. This system enables the harmonics measurement, which is difficult before, of the switching regulator in 40 to 100MHz band. The […]
Air interface simulation for wireless communication
Application of High-speed programmable attenuator The radio wave radiated from a wireless communication equipment changes variously while passing the air. Therefore, it should be confirmed enough that the wireless communication […]
Good way to master the EMI precompliance test system
Abstract As for the EMI test, it is evaluated whether the radiated emission or the conducted emission discharged from EUT (Equipment Under Test) exceeds the limit value set beforehand. This […]
Near field and far field
When the electric field strength and the magnetic field strength are measured, how much the distance between the transmission and the receiving antennas should be always becomes a problem. It […]
Radiated emission measurement comparison between MR2300 and anechoic chamber
The noise radiated from CNE (comparison noise emitted) widely used for the calibration such as anechoic chamber was measured with both of MR2300 and anechoic chamber, and the measurement results […]
Measurement in band from 9 to 13GHz by parabolic antenna with down-converter
Concrete application example The signal of band from 7.9 to 14.5GHz is received by a parabolic antenna, and then it is converted to the lower frequency from 50kHz to 3.3GHz […]
Measurement by MSA338 before installing wireless LAN
The radio wave environment around the installation place must be measured before the wireless LAN is installed, and then the spot installed and the channel used are decided. The setting […]
Measurement of radio wave of wireless LAN by MSA338
Floor arrangement The measurement example using MSA338 is explained by “Floor arrangement” of the figure below. The electric field strength is measured in th e parts enclosed with circle from […]
