on each test point are showed in the following descriptions.
● C1842/C1844
Check whether Transceiver B6PLD (U1802) operates normally or
not. U1802 needs to be replaced if improper RF power, no power or
lower power than that on the golden sample, is measured on C1844
and C1842. C1844 is the test point for GSM900 band. C1842 is the
test point for DCS1800 and PCS1900 band. The following figures,
which sequentially indicate measurement result of GSM900 on C1844
and DCS1800/PCS1900 on C1842, are examples of RF signal
measurement on the spectrum analyzer.
