Immunity measurements of TV and FM/AM receiver in GTEM-cell

GTEM-cell (giga-hertz transversal electromagnetic cell) structure was used to test the immunity of the TV and FM/AM receiver. It has uniform electromagnetic field in the area where the equipment under test (EUT) is placed. The loaded and unloaded GTEM-cell is modeled by finite element method. Voltage standing wave ratio (VSWR) and return loss of the GTEM cell were measured, as well as the field distribution inside the cell with the probe. The insertion of the TV monitor changes the electric field, so the measured results must be calibrated. The tested TV monitor and FM/AM receiver did meet the standard requirements.
