An on-site fast test system based on a novel miniaturized GTEM cell

This paper proposes an on-site fast test system for EMC measurement. It introduces the principle of GTEM cell at first. Then, a novel miniaturized GTEM cell is proposed based on the theory and calculation methods of GTEM cell's characteristic impedance and interior strength of field. It is small in size and convenient to move, specially designed for EMC site fast test. The models of GTEM cell are built in HFSS according to the different size of equipment under test (EUT). The hardware system is constructed with a GTEM cell, a signal generator, a power amplifier and a field strength monitor. Finally, an automatic test system is designed by Labview which can control each device above to complete the on-site fast test.
