Measuring antenna signal strength with automatic gain control receiver |
摘要 |
Apparatus and method for measuring an antenna signal strength (X). The apparatus includes a first amplifier section (3) for receiving an antenna signal and having a first automatic gain control stage; a second amplifier section (8) having a second automatic gain control stage; an automatic gain control system (12; 16') for generating automatic gain control signals (VRF AGC, VIF AGC) for the first and second amplifier sections in accordance with a delayed automatic gain control scheme with a take-over-point. In order to measure the antenna signal strength, the take-over-point is automatically shifted towards the actual antenna signal strength.
