SPORTON INTERNATIONAL INC. TEL : 886-3-327-3456 FAX : 886-3-328-4978 D2450V2, serial no. 736 Extended Dipole Calibrations Referring to KDB 450824, if dipoles are verified in return loss (<-20dB, within 20% of prior calibration), and in impedance (within 5 ohm of prior calibration), the annual calibration is not necessary and the calibration interval can be extended. <Justification Procedure of Extended Dipole Calibration> 1. Setup a Network Analyzer (Agilent N5230A) and set the start frequency and stop frequency to Network Analyzer according to the dipole frequency, at least +/- 200MHz around the calibration point. 2. Using calibration kit to perform Network Analyzer Open, Short and Load calibration. 3. Connect the dipole with the calibrated Network Analyzer. 4. Place the dipole underneath the phantom which is filled with head-simulating or body-simulating liquid. 5. Set the Network Analyzer frequency by the dipole calibration frequency. Monitor the return-loss and impedance results with Log Magnitude format and Smith Chart, respectively. 6. Record the result and compare with the prior calibration. Please check the Appendix C for detail records. <Justification of the extended calibration> D2450V2 – serial no. 736 2450 Head 2450 Body Date of Measurement Return-Loss (dB) Delta (%) Real Impedance (ohm) Delta (ohm) Imaginary Impedance (ohm) Delta (ohm) Return-Loss (dB) Delta (%) Real Impedance (ohm) Delta (ohm) Imaginary Impedance (ohm) Delta (ohm) 7.25.2011 -27.042 54.398 1.4805 -30.696 50.812 2.8262 7.25.2012 -27.950 -3.365 52.541 1.857 0.77343 0.707 -31.781 -3.535 50.572 0.24 1.5953 1.2309 The return loss is < -20dB, within 20% of prior calibration; the impedance is within 5 ohm of prior calibration.
