The constant-fraction technique provides optimum time resolution over a wide range of pulse amplitudes. Exclusive features of the CF8000 discriminator include internal shaping delay, automatic walk adjustmetn, an analog summation output, and built-in logic functions to minimize external logic requirements.
All outputs have adjustable widths.
LEMO connectors are used for maximum packing density. External delay cables are not necessary on the CF8000 discriminator. For all delay plug-ins, there are five possible delay settings. The constant-fraction ratio is factory set at 0.4. 30-ns delay settings.
