This paper presents the use of a GTEM in an interlaboratory comparison. The GTEM cell is Gigahertz Transverse Electromagnetic waveguide, which has its operation described in IEC 61000-4-20. The comparison program of radiated emission was lead in accordance with CISPR 22, standard that normalizes limits and methods of measurement of radio disturbance for information technology […]
This paper describes methods to measure and characterize propagation channels for terrestrial Digital TV in Brazil, where the standard adopted is the ISDB-Tb (Integrated Services Digital Broadcasting Terrestrial Brazilian). Measurements were taken using a Drive Test to acquire the values of parameters that allowed the analysis of signal quality. This test is performed by a […]
This paper aims to analyze a possible limit for harmonic current emissions at voltages below those provided by IEC 61000-3-2. It shows a comparison between the odd harmonics of several devices belonging to class B and D, and the harmonics of a device belonging to class C, at the voltages 230 V, 127 V, and […]
