Abstract
According to examples, a test instrument may include a radio frequency (RF) receiver to receive RF signals across a range of frequencies, a persistent spectrum analyzer to determine signal strengths of the RF signals across the range of frequencies, and a processing circuit. The processing circuit may determine respective hit rates of the RF signals from the determined signal strengths of the RF signals, detect that a certain RF signal of the RF signals is an interference signal based on the respective hit rates of the RF signals, and output the frequency of the detected interference signal. The use of the hit rates may enable identification of interference signals have relatively low signal power levels.
