摘要： A method for gain calibration of a gamma ray detector includes measuring signals generated by one or more light sensors of a gamma ray detector, generating one or more derived curves using the measured signals as a function of bias voltage and identifying a transition point in the one or more derived curves. The method also includes determining a breakdown voltage of the one or more light sensors using the identified transition point and setting a bias of the one or more light sensors based on the determined breakdown voltage.

摘要： A processor for a cable television set-top box has an interface for coupling the processor to a second processor. The processor also has a port that is coupleable to control a tuner, a demodulator and a DOCSIS module with or without DSG support. The tuner has an output coupled to the demodulator input, and the demodulator has an output to the DOCSIS module input. The demodulator's output is also coupled to a conditional access module controlled by the second processor. The processor issues commands via the port to control at least one of the tuner and the demodulator based on instructions received via the interface from the second processor.
