Fig.1:Attenuation of MAT800\/810 corresponding to 16-frequency range.<\/p>\n<\/div>\n\n

The attenuation level of MAT800\/810 has some frequency response that is higher at minimum frequency \"\u01920<\/sub>\" and maximum frequency \"\u019215<\/sub>\" and lower at the center frequency \"cf\" as shown in Fig.1. Therefore, the attenuation levels are calibrated ac cording to 16 frequency ranges, from \" \u01920<\/sub>\" to \"\u019215<\/sub> \", by 1600 steps(MAT800) or 1200 steps(MAT810). <\/p>\n

MAT800 has 1600 step of attenuation level, 0dB to 80dB by 0.05dB step. <\/p>\n

MAT810 has 1200 step of attenuation level, 0 dB to 60dB by 0.05dB step. <\/p>\n

The attenuation levels are corrected for all 1600(M AT800) or 1200(MAT810) step using a SG and a power-meter. <\/p>\n

In the case you use MAT800\/810 at \"\u0192i<\/sub>\" frequency or around \"\u0192i<\/sub>\", you select a frequency range using the keys and the data-knob of MAT800\/810, and the MAT800\/810 make a attenuation level corrected at the frequency \"\u0192i<\/sub>\". <\/p>\n

By above correction, MAT800\/810 is improved to mak e correct attenuation level for all frequency range. <\/p>\n\n
