BB ADC-Readings
Test description:
Open the ADC Reading Test Menu from the Testing drop down menu.
Perform the Test:
There are no Base band Alignments to be done, only the AD-Values should be read out to
check if the inputs of the AD-Converter have the right levels. The BSI and BTEMP line can
be checked with the Local-Mode switch and the VEB-Power (replacement for the Phone
battery) voltage can be read out. To control this value the real Voltage should be con-
trolled by Voltage-Meter. The Testing Limits can be seen in Table below:
