maximum emission level.Bilong antenna(calibratedby Dipole Antenna)is used as a

receiving antenna .Both horizontal and vertical polarization of the antenna are set on test.

The bandwidth of the Receiver(ESCS30)is set at 120kHz.

All the scanning curves are attached in Appendix I.

9.4EUT Configuration on Test

The configuration of the EUT is same as Section 3.4.

9.5 Test Procedure

The EUT is places in the middle of a induction coil (1*1m), under which is a

1*1*0.1m(high)table,this small table is also placed on a larger table,0.8m above

the ground. Both horizontal and vertical polarization of the induction coil are set

on test,so that each side of the EUT is affected by the magnetic field. Also can

reach the same aim by change the position of the EUT.
