DA-TYPE SOCKET ASSEMBLIES DEC. 2000 C7247 SERIES The C7247 series is a DA type socket assembly designed for 28 mm (1-1/8 inch) diameter side-on and head-on photomultiplier tubes. The C7247 series socket assembly incorporates a voltage-divider circuit and a current-to-voltage conversion circuit along with an amplifier having a wide bandwidth (0 Hz to 5 MHz). The C7247 series converts the low-level, high-impedance current of a photomultiplier tube into a low-impedance voltage output by a factor of 0.3 V/ µA. Since the C7247 series employs an active voltage-divider circuit, it ensures an excellent DC linearity at low power consumption.
