| Abstract(in English) | We conducted a research to clarify the probable cause of the measurement errs. We found that, when a range of broad band noise is measured using a receiver and spectrum analyzer which conform to the CISPR 16 standard, the measurement errs between the QP(quasi-peak)values can reach up to 8dB at the radiated emission noise tests, and reach more than 30dB at the conducted emission noise tests. we propose to revive the once-available CISPR 16 document for current use, as this document described that, in case of a doubt, the value at the receiver side should have the priority. We also found that, at a specific frequency range, the signal transfer line of the measuring system indicated loss of about 10dB, just because of an incomplete contact at the coaxial connection switch. Similarly, we encountered a phenomena that the antenna factor suddenly changes and its cause was found to be an incomplete contact a single element. In order to prevent occurrences of these measurement errs, it is necessary to confirm the transmission loss and reception sensitivity for the whole frequency range prior to a test. |
