ABSTRACT:
An amplifier array includes a servo amplifier, which has a reference signal input, a return signal input, and an output signal connection, which supplies an output signal path, a reference signal generator, which supplies reference signals with different level heights to the reference signal input, and with a return, which supplies a signal, attenuated by a value of the feedback attenuation, from the output path as a return signal to the return signal input, whereby the servo amplifier supplies an amplified difference between the reference signal and return signal in the output signal path. The amplifier array has a connectable bypass gain path, which in the connected state is supplied phase-coupled to the reference signal generator and which supplies a bypass output signal in the output path.
