RH-128
Service Software Instruction
H. Turn on the transmitter using the Tx Rate. Set the Rate is Tr Full Rate.
I. Set up the spectrum analyzer or test set to measure the channel power on the same channel
selected in step F.
J. Vary the HW Val until the reported power is /-1 dB of the desired power level using DSPM
Tx AGC Config.
K. Store the reported test set channel power (dBm) versus PDM value point in the non-volatile area of
flash memory.
L. Iterate steps G to K for all desired calibration points and Write to store the values.
M. Repeat steps G – L for all desired gain points.
CDMA TxAGC Frequency Channel Adjustment
CDMA TxAGC Frequency Channel Adjustment overview
To perform this calibration, the baseline Tx AGC calibration should have already been performed. This is
performed for all gain states.
CDMA TxAGC Frequency Channel Adjustment Procedure
A. Perform the procedure at “nominal” or room temperature.
B. The baseline RxAGC calibration must have already been completed.
C. The RxAGC frequency channel adjustment, and temperature adjustment tables must be zeroed.
D. Connect the antenna to CDMA test set.
E. Reset the UUT, start Debugtool, and do not press the Power key on the Virt MMI (i.e., PS should
be off and LID reset). Send the message CP Enable, with Disable option.
F. Turn off the transmitter test using the Tx Rate Test with the rate set to Tr Full Rate.
G. Set the frequency channel to the channel used for calibrating the TX AGC using the PLL Channel
Config. CP PLL Channel Config Settings, Ctrl Mode: Manual, Band: Band being calibrated, Channel:
Channel being calibrated.
