1. A circuitry comprising:
a first attenuation circuitry coupled between a first terminal of a signal processing chain and a measurement apparatus; and
a second attenuation circuitry coupled between a second terminal of the signal processing chain and the measurement apparatus, wherein the signal processing chain is configured to apply one or both of a gain change or a phase change to signals passed between the first terminal and the second terminal of the signal processing chain, and one or both of the gain change or the phase change applied to the signals is measured by the measurement apparatus;
wherein the first attenuation circuitry and the second attenuation circuitry are configured to selectively attenuate first signals provided from the first signal processing chain (SPC) terminal to the measurement apparatus or second signals provided from the second SPC terminal to the measurement apparatus to reduce a difference between a first signal power of the first signals provided from the first SPC terminal to the measurement apparatus and a second signal power of the second signals provided from the second SPC terminal to the measurement apparatus.
