No.7（2012）21.Evaluating the 10m method anechoic chamber and experimenting on the influence of a second mast in the double mast system
Fumio Takahashi, Hiroyuki Ohashi, Manabu Oomori
To obtain ISO17025 accreditation for the 10m method anechoic chamber in the Tama techno plaza, the following action items are needed; i) creating written procedures needed for ISO17025 accreditation, ii) listing and checking the uncertainty factors in the measurement system, and iii) calculating the uncertainty in the whole EMC system.
In order to meet the technology requirements of ISO17025, the characteristics are evaluated and some improvements to the 10m method anechoic chamber are made. Furthermore, experiments were carried out to test the influence of a second mast in the double mast method system in the Tama techno plaza which achieved a higher-speed measurement.
