147 6.5 Measurement on drums
148 Unless otherwise specified or special cable-specific characteristics need to be taken into account, the cables
149 shall be measured on drums or coils.
150 7 Measurement methods and equipment
151 7.1 Calibration
152 Equipment calibration shall be considered part of the quality system.
153 7.2 Requirements for balanced to unbalanced converters (Baluns)
154 Several classes of baluns with different performance levels are defined. This is in order to facilitate
155 measurements in different frequency ranges with commercially available baluns as appropriate. The baluns
156 may be balun transformers or 180° hybrids with attenuators to improve matching if needed (see Figure 1).
157
158 Figure 1 — 180° hybrid used as a balun
159 Baluns shall be RFI shielded and shall comply with the requirements given in Table 1. Depending on the
160 frequency range different requirements are specified. For frequencies higher than 1 GHz balunless
161 measurement technique is recommended (see clause 7.3).
162 Generally, it is advantageous to choose a balun with the same common mode impedance as the cable under
163 test. However, in practice this is hardly possible as it is unreasonable to provide separate measurements
164 equipment for each cable type. Often the best performance for differential mode is achieved when the centre
165 tap of the secondary winding of the balun is grounded; meaning the nominal common mode impedance is
166 25 Ω. Then the results can directly be compared to results achieved by balunless measurement technique
167 when 50 Ω ports are used without mathematical impedance transformation of the latter results.
168 In case of balance measurements the centre tap of the secondary winding of the balun cannot be grounded.
169 To compare balance measurement results achieved with balun-based measurement technique to results
170 achieved with balunless measurements technique the procedures described in EN 50289-1-9 shall be
171 considered. Unless otherwise specified the rules specifying the common mode termination for balance

172 measurements according to EN 50289-1-9 shall be applied in case of doubt. The reference common mode
173 impedance specified accordingly may be different to the reference common mode impedance of the cabling
174 system the cable is intended to be used for.
