cursor keys.
Calculate button (ALT+A):
The calculation is activated with this button. The power coefficients, which are calcu-
lated from the tuned coefficients, are displayed on the different as right-justified values
in the list box. All values can be tuned if needed.
Base level calculation check box:
If this box is checked, the Base level is calculated.
+/- buttons (+/- and left/right cursor keys):
The + and - buttons will change the power in 0.25 dB steps. When these keys are used,
the coefficient value is updated in the tuning window.
Save button (ENTER):
Dialog is closed and tuned values are saved to phone.
Cancel button (ESC):
Dialog is closed and tuning is not saved to phone.
When selections are made, the power value checking is done and if it is not successful,
an error message is shown. The test checks that all power coefficients are in descending
order (same order as power levels).
If the power tuning function is ended and EEPROM values are not received or an
EEPROM fault is noticed, an error message is shown.
When all power coefficients have values that don’t cause error messages, a Save can be
made. The last used tuning power is in use after exit.
The next automatic selection is made and the RF information window is updated when
the next tuning function has ended:
Active Unit = RX
TX Power Level = (Off)
Operation Mode = Burst
Tx I/Q... command
A GSM/PCS signal tester or a GSM/PCS Spectrum analyzer and an antenna cable is
needed for the tuning. Before starting the Tx I/Q tuning, the active band is set to the
GSM band.
