3.2.1 – TX Power Tuning
This function is used for tuning power levels.
The next question is made to the user:
Values from EEPROM? (YES/NO) _
The user is also informed that TX power will be connected to biggest value if he
does not break the selection with <Esc> key.
If <Y> key is used, tuning values from EEPROM will be loaded. If <N> key is
given, the values which PC program normally uses when DSP is controlled will
be used. If <Esc> key is used the selection is interrupted and the previous
menu is shown on the screen. Nothing happends if any other key is used.
The next tuning window will be activated automatically after value selection.
The power is presented in PCS values (0...15) and the TX power base level in-
dicated by ”base” text. The base level is selected automatically when the func-
tion is started. The test value is always same when the function is started first
time after PCLocals start–up. The test value is not saved to the EEPROM. The
test value can be changed during tuning as other power coefficients and the
program remembers its value when tuning function is activated later again.
There is one selection which is used for power coefficient calculation. Only five
power coefficients (Power levels 0,5,10,11 and 15) are needed to tune and the
rest of them will be calculated.
The calculation is activated by using <F3> key. The power coefficients which
are calculated from the tuned coefficients are displayed on the different col-
umns than the others. All values can be tuned if needed.
