Abstract
A monitoring device in an analog-to-digital converter, the monitoring device including a monitoring module configured to receive a first radio frequency signal provided by a first radio frequency modulator and a second radio frequency signal provided by a second radio frequency modulator. The first radio frequency signal being associated with a laser data and a radio frequency input signal. The laser data being associated with a radio frequency oscillator signal. The second radio frequency signal being associated with the laser signal and the radio frequency oscillator signal. The monitoring module is configured to determine a modification factor based on the first radio frequency signal and the second radio frequency signal.
