Page 13: Measurement
2 Measurement Determining the Interference Source Impedance Zs Generally, interference sources have low impedance so that measurements using the R&S ESH2-Z3 produce correct results. Though, the levels measured with an undefined source impedance may be incorrect. In order to determine the impedance Zs of the interference source, first measure the level without and then with attenuator 6 at a test frequency complying with CISPR Publication 16-2-1, Section 2.4.6.2 (see Fig. - Page 14 R&S ESH2-Z3 Measurement Test point ESH2-Z3 Measuring M.
