In Phoenix select connection Fbus and Product Gemini. If you power up the board before se-
lecting Fbus, it works without any error messages.
Use Jig or other device for RF and bus connection. Attenuation in the probe alone is 0.5dB for
900 and 1dB for 1800. Use CMD55 or other suitable device. Default channels are 37 for
GSM900 and 700 for GSM1800. The alignments and calibrations must be performed in the or-
der 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.
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.
