1. A method for monitoring a radio frequency (RF) receiver, the method comprising:
receiving a first signal;
generating, based on the first signal, a digital test signal, wherein the digital test signal comprises a stream of digital test samples, and wherein the stream of digital test samples comprises a first digital test sample;
generating a monitoring signal based on the digital test signal;
coupling the monitoring signal into a receiver path;
processing the monitoring signal in the receiver path to generate a processed monitoring signal;
generating a stream of digital monitoring samples representing the processed monitoring signal;
determining first information indicating at least one property related to the receiver path based on a processing of a set of digital monitoring samples, wherein the set of digital monitoring samples comprises a portion of the stream of digital monitoring samples, and wherein the set of digital monitoring samples comprises a first digital monitoring sample; and
controlling the RF receiver such that the first digital monitoring sample of the set of digital monitoring samples is generated at a predetermined time duration after generating the first digital test sample of the stream of digital test samples.
