CDMA In Call Testing (High Gain)

AGC Tolerances for -105dBm Input
Band
Cell CDMA
PCS CDMA
1. Adjust the call box sector power to -105dBm. This turns the LNA to High Gain.
2. Compare the RSSI reading with the sector power on the call box. The value
should be accurate to +3dB.
3. Compare the Tx power to the digital average power on the call box.
4. Verify that all PDMs for Rx and Tx are within tolerances specified in the above
table.
• Cell: Tx power (dBm) = -73 — RSSI
• PCS: Tx power (dBm) = -76 — RSSI
