ABSTRACT:
A system, and associated method, for measuring a signal level of a signal received by a receiver, such as a radio telephone. The signal received by the receiver is applied to a variable amplifier. The amplification of the variable amplifier is adjusted such that an amplified signal generated therefrom is within the dynamic range of an intermediate frequency circuit. The level of amplification required to position the signal level of the amplified signal within the dynamic range of the intermediate frequency circuit is measured, and the signal level of the signal received by a receiver is calculated.
