Abstract: As a VHF filter device, the harmonic filter in DF100A&418E/F series of shortwave transmitter plays an important role in the safe broadcast work of transmitter of the parameter data and good or bad quality after adjustment and measurement. Therefore, this paper introduces in detail the method of using Agilent E5061A network analyzer to adjust and measure the harmonic filter of DF100A&418E/F series of shortwave transmitter, focusing on the comparison of the results and effects of harmonic filter single-port and dual-port adjustment and measurement, in order to solve the problems encountered in actual maintenance through the analysis of actual adjustment and measurement data.
Keywords: DF100A&418E/F series short wave transmitter; harmonic filter; Agilent E5061A network analyzer; single-port disadvantage; dual-port advantage
