Alignment
■ Manual alignment with Phoenix
The alignment/calibration is the same in both GSM900/850 and GSM1800/1900 except for the
channels and frequencies. Only the the procedures for GSM900/GSM1800 are shown.
In Phoenix select connection Fbus scan product. If you power up the board before selecting
Fbus, it works without any error messages. Use Jig or other device for RF and bus connection.
Attenuation in the probe alone is 0dB for 900 and 0.1dB for 1800. Use CMD55,CMU200 or oth-
er suitable device. Default channels are 37 for GSM900 and 700 for GSM1800 (Ch 190 and
661 for GSM850/1900). The alignments and calibrations must be performed in the order shown
to give reliable results.
The way to save data to the phone and to load data from the phone is made different in the
various tunings. Always look what is shown in the windows regarding these issues and act ac-
cordingly. In some windows the saving is done without any warning or second approval as soon
as you stop or end.
To vary a selected parameter you can use + and – key or in some cases directly type the new
value. + and – steps the value for every press. Repeat function seems not to work. In I/Q you
can use the side arrows.
