CDMA In Call Testing (Low Gain)

AGC Tolerances
Band
Cell CDMA
PCS CDMA
1. In a call, handoff to the center channel (channel 600 for PCS, or channel 384 for
Cell) and verify that the call box sector power is –65dBm. The LNA will be in Low
Gain.
2. Compare the RSSI reading on the RF AGC Status dialog box with the sector
power. Compare the Tx power to the digital average power on the call box. The
value should be accurate to +3dBm.
3. Verify that Cell PDMs for Rx and Tx are within the specified tolerances:
• Cell: Tx power (dBm) = -73 — RSSI
• PCS: Tx power (dBm) = -76 — RSSI
