Abstract
Methods and apparatus for a detector system having a photodetector and an amplifier to amplify the photodetector signal. A discriminator generates an active output signal when the output from the amplifier is greater than a threshold. An injection circuit is coupled to the input of the amplifier. The injection circuit is configured to selectively inject a test pulse that mimics a pulse from the photodetector for verifying operation of the detector system.
