C7246 SERIES
PATENT
The C7246 series is a DA type socket assembly designed for 28 mm (1-1/8 inch) diameter side-on and head-on
photomultiplier tubes. The C7246 series socket assembly incorporates a voltage-divider circuit and a current-to-voltage
conversion circuit along with an amplifier that has a narrow but practical bandwidth (0 kHz to 20 kHz) to improve the
effective S/N ratio.
The C7246 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 C7246 series employs an active voltage-divider circuit, it ensures an excellent DC linearity at low power
consumption and a gain adjustment function that does not affect the frequency bandwidth of the amplifier.
