A signal monitoring system includes a conversion circuit and a controller coupled to the conversion circuit. The conversion circuit converts a reference input to a reference output based on a real-time level of a trim reference and converts a monitored signal to an output signal. The controller calibrates the output signal according to the reference output and according to a predefined reference. The predefined reference is determined by the reference input and by a pre-trimmed level of the trim reference. |
