1. A method comprising:
disabling, by a control unit of a receiver, a dynamic gain adjustment via a dynamic gain amplifier of the receiver, wherein the receiver further comprises at least one static gain amplifier coupled to an input of the dynamic gain amplifier to generate a static gain amplified signal by applying a static gain to an input signal;
configuring, by the control unit, the dynamic gain amplifier to apply, via the dynamic gain amplifier, a predetermined fixed gain to the static gain amplified signal to generate a test signal;
determining, by the control unit, an effective static gain magnitude of the at least one static gain amplifier and an effective amplitude of the test signal for which a link performance metric of the receiver is identified to be at a target performance value;
setting, by the control unit, the static gain of the at least one static gain amplifier to the effective static gain magnitude, and a target amplitude for the dynamic gain amplifier to the effective amplitude of the test signal; and
enabling, by the control unit, the dynamic gain adjustment via the dynamic gain amplifier to maintain an amplitude of a dynamic gain amplified signal at an output of the dynamic gain amplifier at the target amplitude by varying a dynamic gain of the dynamic gain amplifier.
