UNE EN IEC 61788-7:2020
This part of IEC 61788 describes measurement of the surface resistance of superconductors at microwave frequencies by the standard two-resonator method. The object of measurement is the temperature dependence of Rs at the resonant frequency. The applicable measurement range of surface resistances for this method is as follows: Frequency: 8 GHz < f < 30 GHz Measurement resolution: 0,01 m© at 10 GHz The surface resistance data at the measured frequency, and that scaled to 10 GHz, assuming the f 2 rule for comparison, shall be reported.
