The PA120A is a particularly fast DC-coupled power amplifier. Its power bandwidth is 1.5 MHz.
The output stage of the PA120A delivers output voltages between –30 V and +30 V, providing the user with output currents of ±4 A and peak output currents of up to ±10 A.
The amplifier has two input channels, the signals from which are summed. This makes it possible, for example, to add a DC offset to an AC signal or to superimpose a useful signal onto an interference signal. For both input channels, the input resistance (50 Ω / 10 kΩ), coupling mode (AC / GND / DC) and gain (x1 / x10) are switchable.
