Service Software Instruction
I. Turn on the transmitter test using the Tx Rate with the rate set to Tr Full Rate.
J. Set the Target Tx Power by direct control of the dBm setting using DSPM TxAGC Config. Vary the
HW Val until the reported power is /-1 dB of the desired power level using DSPM Tx AGC Config.
DSPM Tx AGC Config Settings, Ctrl Mode: Manual, Method: dB Gain ,HW Val: N/A, Hyst State: N/A,
Power (dBm): Some starting value
K. Set the measurement equipment to the measurement frequency channel.
L. Get the Measured Tx Power (over the 1.25 MHz bandwidth) from the CDMA test set (or other
measuring device) and get the Closed Loop Tx Power from the Current Tx Power.
The true power calculate: Read Power / 64 = True Power (dB)
M. Calculate Power Error = Measured Tx Power - Closed Loop Tx Power .
N. Store the Power Error (dB) versus frequency channel point.
O. Iterate steps 7, 10-12 for all desired calibration points.
P. Write calibration parameters to the non-volatile area of flash memory
