The method of evaluating disturbances from the kit-modules, such as a ha
rd disk and a memory, has been proposed and is carried out by VCCI. In t
his method, the disturbance level is evaluated by a disturbance current
on power supply line. In recent years, the processing speed of electrica
l equipment is increasing and the disturbances above 1 GHz appears on po
wer supply line. Therefore, we should develop the method of evaluating d
isturbance for the kit-modules above 1 GHz. The disturbance level of the
kit-modules is evaluated by using the test board which is constructed w
ith the micro strip line decoupled by chip capacitor. In frequency range
of above 1 GHz, the disturbance level on the line changes by the influe
nce of the standing wave. The maximum level should be obtained by the cu
rrent level on many points of the line in order to reduce the influence.
In addition, the effect of chip capacitors should be confirmed.
In this report, the current distribution on the test board is calculate
d by using the FDTD method and it is evaluated by the measurement result
. As a result, when the measurement is carried out at the nearest positi
on of the chip capacitor, the deviation from the maximum level is within
1 dB. |
