Basis of Calibration #1

  What is Calibration?
    Calibration Program is used to adjust a hardware
     characteristic that is specific to each phone. (tuning the all
     the parameters to access the hardware)
    Through this the mobiles can operate in the most optimized
     condition
  Equipments
    PC : Microsoft Windows Base
    Wireless Communication Test Set : HP8922, HP8960,
     CMU200
    Programmable Power Supply : GPIB Programmable E3632A,
     HP6632, IPS 18B10, HP66311B
    GPIB(General Purpose Interface Bus) Card
    JIG Converter
    RS232 cable
      – 9 pin RS232 cable(connects PC with JIG)
      – 25pin RS232 cable(connects Mobile with JIG)
