WIDE BANDWIDTH AMPLIFIER UNIT
C6438-02
The output signal from a photomultiplier tube can be di-
rectly input to the C6438-02 and it provides a voltage out-
put 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.
