RF-based beam diagnostics such as BPMs and beam current monitors rely on precise RF signal measurements. Temperature drifts and differences in the overall measurement chain gain make such measurements very challenging and calibration validity over time is an issue. Over some years, on-line calibration schemes for BPMs and current monitors have been developed. These innovative schemes are based on the use of a pilot signal at a frequency offset from the measurement frequency. Results, advantages and disadvantages of such schemes are discussed.
