(a) Histogram of 10000 frames for a single memory cell of a single pixel illuminated with characteristic X-rays from molybdenum. The gain factor is derived from the mean peak-to-peak distance. (b) Using the internal current source all three gain levels can be sampled. (c) The pulsed capacitor samples only the high-gain state and parts of the medium-gain state. The non-ideal transition between the two gains is caused by the finite bandwidth of the calibration circuit.
