Claim Text:
1. A method for acquiring spectral information from an energy sensitive nuclear detector comprising: detecting nuclear radiation at a detection device and generating an electronic input pulse indicative of energy deposited in the detection device; integrating the electronic input pulse at an integrating device to produce an integrated output signal; digitally sampling the integrated output signal of the integrating device at intervals to produce a stream of digital samples; and resetting the integrator synchronously with a sampling clock when a limit condition is reached, further comprising determining and calibrating the integrated output signal during a quiescent period of the integrating device, wherein the integrating device produces the integrated output signal as a difference between a first sample after an end of integration of the electronic input pulse and a sample preceding a start of the electronic input pulse compensated by a quiescent integral for a same length of time.
