The return-loss does not deviate more than 20% from the previous measurement and meets the required 20 dB minimum return-loss requirement. 3. The measurement of real or imaginary parts of impedance does not deviate more than 5Ω from the previous measurement. The following dipole was checked to pass the above 3 requirements to have 3-year calibration period from calibration date.
