Set the WCDMA receiver to factory calibration settings
This command configures the WCDMA receiver according to factory
calibration settings stored in the modem's NV (Non-Volatile memory). This
allows for accurate measurement of RX AGC levels.
The command performs these steps:
1. Sets the channel
2. Selects and sets LNA range (or LNA gain)
3. Sets the VGA gain offset based on the channel
4. Sets the LNA range offset
Parameters (Input):
<channel> (Uplink channel number (ARFCN)):
• value based on the selected band
<Rx_Level_dBm> (approximate signal level (in dBm) being applied to the
modem receiver):
• Valid range: -113 to 20
Parameters (Output):
<LNA Index> (LNA offset index):
•
0 = R0 (highest gain)
• 1 = R1
• 2 = R2
• 3 = R3 (lowest gain)
<DVGAOffset>
•
Internal use only
<LNA Value>
