Disturbance Voltage at Antenna Terminal.
4.4.1 Site and Test Description
Testing was performed in accordance with CISPR 13.
When measurements are made at the antenna terminals of the EUT, a signal generator shell be used to feed
the EUT with a standard test signal.
The Antenna Terminals of the EUT and the Signal Generator are connected to the measuring receiver by
means of coaxial cables and the resistive combining network having a minimum attenuation of 6 dB.
The Impedance seen from the EUT shall be equal to the nominal Antenna input impedance for which the
EUT has been designed. If the output impedance of the signal generator and the input impedance of the
measuring receiver differ from the value, additional matching network and/or attenuators of minimum value
of 6 dB shall be inserted.
