ČSN EN IEC 61788-7 ed. 3

This part of IEC 61788 describes measurement of the surface resistance (Rs) 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 Rs for this method is as follows: - Frequency: 8 GHz < f < 30 GHz - Measurement resolution: 0,01 m at 10 GHz The Rs data at the measured frequency, and that scaled to 10 GHz, assuming the f 2 rule for comparison, is reported.
