WIDE BANDWIDTH AMPLIFIER UNIT C6438-02 The output signal from a photomultiplier tube can be directly input to the C6438-02 and it provides a voltage output signal with 50 Ω load at a conversion factor of 5 mV/µA. The C6438-02 has a selecting switch to get the amplified non inverting-inverting output.
