Service Software Instruction
The Spy windows become active, and display the current Tx and Rx status.
G. Get the RxDAgc Value Bitsel and the RxDAgc Value Gain. Write those calibration parameters
together with Reference Level to the non-volatile area of flash memory. To confirm the new calibration,
first update the Flash by either power cycling the UUT or by using the CalMode Select with the NVRAM
option.
H. Calibrate the Gain offset. Set the test set transmission power to the desired power which is
between the switch point of each gain level. Calibrate the gain level from the high gain to low gain. Set
the calibration RxAGC gain state by clicking on DSPM Rfc Dagc.
I. Get the received power form the Spy window. For example, if the BS power is -85dBm, and the gain
state is 3, we get -96dBm from spy window. The offset of gain 4 to gain 3 is -85 – (-96) = 11dBm. Write
the calibration parameters to the non-volatile area of flash memory. Confirm the new calibration result.
J. Iterate steps H - I for all desired calibration points.
CDMA RxAGC Frequency Channel Adjustment
About CDMA RxAGC Frequency Channel Adjustment
This procedure is performed at only one power setting. This procedure assumes that the baseline
RxAGC calibration table has been loaded into NVRAM. However, if the calibration application (running
on a PC) stores the RxAGC tables from Section 7.2.1 in PC memory, then the PC Application can
interpolate dBm power values from the PDM value returned by Debugtool. More details are provided
below in the steps below.
