IEC 61788-7:2006 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 milliohm at 10 GHz.
