RH-128
Service Software Instruction
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. Set the test set Transmission Power to a desired power point (-100 dBm is a suggested value). This
is normally a point that is calibrated during Rx AGC calibration.
G. Set the test set frequency channel to the test frequency. For the first data point, enter the channel
used to calibrate the RX AGC.
H. Set the frequency channel to the calibration frequency using the CP PLL Channel Config. For the
first data point, enter the channel used to calibrate the RX AGC. Set the Control mode as Manual, the
band to target band.
I. Allow for 25 ms (or more) of settle time.
J. Get the RxAGC Antenna Power (dBm) value using the DSPM Rx AGC Get Parms. As show in the
picture, we get received power -101.1dBm.
K. Calculate Error Power = Transmission Power – Antenna Power, where the Transmission Power
was set in step F and the Antenna Power was obtained in step J. Store the Error Power (dB) versus the
frequency channel point in the non-volatile area of flash memory.
L. Iterate steps G - K for all desired calibration points.
CDMA TxAGC Calibration
There are multiple tables for calibration of the transmitter. All curves must be generated for all band
classes and for all Tx hysteresis states that are utilized.
Supported Transmitter calibration items are the following:
