In this article, we will consider methods for measuring the electromagnetic compatibility of telecommunication systems and study the norms of compliance with EN 55022 standards. The test equipment is RF (Microwave radio) transceiver equipment. 1.4 GHz. QAM modulation (372 MHz) was enabled in real power mode, and several experiments were also conducted. Experiments show that the parasitic radiation through the image channel at an intermediate frequency in a superheterodyne receiver is 465. At a frequency of 371.94 MHz, deviations at the quasi-peak level are set to 51 dB mv/m.
