With these amplifiers measuring of lowest energies (some 10 nJ with PEM 4) is possible. Due to the amplification and reduction of the capacity load the sensitivity of the detector will be considerably increased. The bandwidth of the amplifiers is specially adapted to this application.

Due to the modular assembly the whole dynamic range will be greatly increased. Additionally, losses of sensitivity by using a smaller load resistor (to increase the possible repetition rate) can be compensated.
