How to tune a Coaxial Filter In Fig.1 is shown the connection between Spectrum Analyzer-Rhotector (VSWR Bridge ) and a Coaxial Filter: Fig. 1. Connections between the instruments. With this kind of connection you can measure the Return Loss or the Standing Wave Ratio of the coaxial filter at port F (shown in Fig. 1), Table 1 reports the relationship between the R.L and the VSWR. Table 1. Return Loss and SWR. The Coaxial Filter is tuned by rotating the four knobs named Lin, Lacc1, Lacc2 and Lout, as in Fig 2. Delta Meccanica provides a graduation and a table for the first position where is better to start the tuning. Fig. 2. Tuning Kobs.
