RH-128
Service Software Instruction
H. Set the measurement equipment to the frequency channel used for calibrating the TX AGC (see
step F).
I. Turn on the transmitter test using the Tx Rate Test with the rate set to Tr Full Rate.
J. Set the Tx power by direct control of the dBm setting using TxAGC Config. DSPM Tx AGC Config
Settings, Ctrl Mode: Manual, Method: dB Gain, HW Val: N/A, Hyst State: N/A, Power (dBm): Middle of
band being calibrated (This is the Target Tx Power).
K. Get the Measured Tx Power from the CDMA test set or other measuring device and calculate:
Antenna Power Error = Target Tx Power - Measured Tx Power
L. Store the Antenna Power Error (dB) versus frequency channel point in the non-volatile area of flash
memory.
M. Iterate steps F to L for all desired calibration points and Write to store the values.
N. Repeat steps F – M for all desired gain points.
CDMA TxAGC Max Power Limit Frequency Adjustment
CDMA TxAGC Max Power Limit Frequency Adjustment overview
In order to perform this calibration, the other Tx AGC calibrations should have already been performed.
This procedure is performed for only one gain state, the highest gain stage, since this table only applies
to max power.
CDMA TxAGC Max Power Limit Frequency Adjustment procedure
A. Baseline TxAGC calibration tables must be loaded.
B. The Tx Limit Freq Chan Adj table must be cleared (write zeros in the DBM template).
C. This procedure is identical to the procedure described in above section, but must be performed at
the Max Power Level.
D. Write calibration parameters to the non-volatile area of flash memory.
