International and/or domestic law.
Several semiconductor may be damaged easilly by static electricity. Such parts are called by
ESD(Electrostatically Sensitive Devices), for example IC,BGA chip etc. Read Precaution below.
You can prevent from ESD damage by static electricity.
●
Remove static electricity remained your body before you touch semiconductor or parts with
semiconductor. There are ways that you touch an earthed place or wear static electricity
prevention string on wrist.
●
Use earthed soldering steel when you connect or disconnect ESD.
●
Use soldering removing tool to break static electricity. , otherwise ESD will be damaged by
static electricity.
●
Don't unpack until you set up ESD on product. Because most of ESD are packed by box
and aluminum plate to have conductive power,they are prevented from static electricity.
●
You must maintain electric contact between ESD and place due to be set up until ESD is
connected completely to the proper place or a circuit board.

-GMSK
1) Procedure:
a. Calibraion equipment HP8960 and the cell phone are connected
through RF cable.
b. Target power ( required power level according to the specification
which should be set by calibration program) is set to equipment as
power level (ex: GSM 5 level is 32.5 dBm).
c. Activate phone in Tx_Mode_Only.
d. HP8960 equipment measures transmitted power through rf test cable
from the phone and reports measured level to calibration program.
Test Command & Test Procedure
e. The program compares measured power with the target power.
f. The calibration program decides power code which is defined in
advance in the program and writes the codes to the flash memory in
the phone.
2) Target value is defined according to the value of GSM specification.
See the TX power level definition table below.
3) Target values of the p eak level of the phone are set normally in
conducted mode
