Characteristic evaluation of conducted disturbance measuring apparatus using two parallel TEM cells

A conducted disturbance measuring apparatus using two parallel transverse electromagnetic (TEM) cells was developed for improving the balance of the conventional apparatus using one TEM cell. However, the balance of the developed apparatus has not been evaluated. In this study, its longitudinal conversion loss (LCL) was measured. As a result, the LCL of the apparatus was obtained as more than 30 dB at the frequency range from 30 MHz to 1 GHz.
