Abstract

See full text

A method for internal calibration of a detector comprising using one or more hardware processors for the following actions. The method comprises an action of receiving a request for internal calibration of a detector comprising a switchable termination resistor (Dicke switch) and connecting electronically one or more internal calibration circuits to the termination resistor. The method comprises an action of applying two or more input voltage signals to the detector from the calibration circuit and measuring two or more output readings from the detector, each output reading corresponding to one of the input voltage signals. The method comprises an action of computing internal calibration coefficients based on the input voltage signals and the output readings. The method comprises an action of storing the internal calibration coefficients on a non-transitory computer-readable storage medium connected to the hardware processor(s) for subsequent calibration of output values from the detector.
