    The silicon drift detector is capable of high energy resolution and high-count measurement of X-rays. The APV8016A can input and measure signals from the SDD detector. The APV8016A has an optimized recovery process from a reset signal to achieve high counting and high resolution. An energy resolution of 126eV@5.9keV is achieved using a Cube-type silicon drift detector.
