The measured SAR does not deviate more than 10% from the target on the calibrationcertificate.
2. The return-loss does not deviate more than 20% from the previous measurement and meets therequired 20dB minimum return-loss requirement.
3. The measurement of real or imaginary parts of impedance does not deviate more than 5Ω fromthe previous measurement.
The following dipole was checked to pass the above 3 requirements to have 2-year calibration periodfrom the calibration date:CertificateElectricalDelay (ns)CalibrationDate
