SINUSOIDAL VIBRATION Vibration Frequencies : 5- 55 Hz (1 cycle) Sweep Rate : 1 cycle/min Maximum Amplitude : A – 1 mm Maximum Acceleration : 2 g Measuring method Antenna is combined in the test equipment. The vibration is done X and Y direction (left, right, up and down) according to below image. It continued for 2 hours each direction. 8. OPERATING TEMPERATURE Temperature : － 30°C / ＋70°C Demands : Set Antenna and Cable for 48 hours each temperature. No visual and mechanical changes. The fitting and mold will be unchanged mechanically during the test. The antenna shall satisfy the electrical data 9. HUMIDITY Condition : 90% ~ 95% / ＋40°C Measuring method Antenna is placed in climatic chamber for 48 hours. Antenna is taken out from the chamber and measured after another 24 hours in room temperature Demands : No visual and mechanical changes. The fitting and mold will be unchanged mechanically during the test. The antenna shall satisfy the electrical data. 10. TEST and Q/C This specification is according to fixed demands and suitable Hanwool technology Q/C provision. But it is possible to skip No. 7~9 demands, after consultation with buyer.
