C6438 is a wide bandwidth, DC to 50 MHz, amplifier. While
providing the photomultiplier tube output current directly to
C6438 input connector, it provides the voltage output signal in
the conversion coefficient of 10 mV/10
A. It can be used as a
wide bandwidth amplifier not only for a photomultiplier tube but
also for other detectors, or simply as a wide bandwidth
amplifier.
