Prior to testing, the measurement paths containing a cable, amplifier, attenuator, coupler or filter were connected to a calibrated source (i.e. a signal generator) to determine the losses of the measurement path.

The measured SAR does not deviate more than 10% from the target on the calibration certifi c ate. 2. The return-loss does not deviate more than 20% from the previous measurement and meets the required 20dB 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 2-year calibration period from the calibration date: Calibration Date Extension Date Certificate Electrical Delay (ns) Certificate SAR Target Head (1g) W/kg @ 20.0 dBm Measured Head SAR (1g) W/kg @ 20.0 dBm Deviation 1g (%) Certificate SAR Target Head (10g) W/kg @ 20.0 dBm Measured Head SAR (10g) W/kg @ 20.0 dBm Deviation 10g (%) Certificate Impedance Head (Ohm) Real Measured Impedance Head (Ohm) Real Difference (Ohm) Real Certificate Impedance Head (Ohm) Imaginary Measured Impedance Head (Ohm) Imaginary Difference (Ohm) Imaginary Certificate Return Loss Head (dB) Measured Return Loss Head (dB) Deviation (%) PASS/FAIL 9/11/20179/11/20181.1525.275.524.74%2.482.542.42%53.849.847.47.10.3-21.9-23-4.80%PASS Calibration Date Extension Date Certificate Electrical Delay (ns) Certificate SAR Target Body (1g) W/kg @ 20.0 dBm Measured Body SAR (1g) W/kg @ 20.0 dBm Deviation 1g (%) Certificate SAR Target Body (10g) W/kg @ 20.0 dBm Measured Body SAR (10g) W/kg @ 20.0 dBm Deviation 10g (%) Certificate Impedance Body (Ohm) Real Measured Impedance Body (Ohm) Real Difference (Ohm) Real Certificate Impedance Body (Ohm) Imaginary Measured Impedance Body (Ohm) Imaginary Difference (Ohm) Imaginary Certificate Return Loss Body (dB) Measured Return Loss Body (dB) Deviation (%) PASS/FAIL 9/11/20179/1…
