Abstract
A method of error vector magnitude, EVM, minimization for a radio frequency, RF, measurement equipment is provided. The method comprises: measuring the EVM of a receive, RX, chain of the RF measurement equipment in accordance with a transmit, TX, feedback signal; and responsive to a trigger event, actuating one or more power-adjusting members interposed in the RX chain in accordance with the measured EVM of the RX chain. Among others, the RF measurement equipment is thereby consistently operated based on optimal power levels in the RX chain.
