Set WCDMA receiver to factory calibration settings
Configure 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.
Usage:
• Execution: AT!DAWSCONFIGRX=<channel>,<Rx_Level_dBm>
Response:
<LNA Index>, <LNA Value>
OK
Purpose: Configure the receiver.
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)
<LNA Value>
• Internal use only
Note: !DASBAND and !DASCHAN must be issued before you can use
!DAWSCONFIGRX .
