These ADC's are specifically intended for digitization of photomultiplier pulses and similar fast transient signals. They are especially well suited to use in large systems because of their low cost, compactness, simplicity of operation, and system- oriented control and test features. They accept and digitize nanosecond pulses directly without need for prior stretching or preshaping of any kind.
Inputs are direct-coupled for freedom from rate effects and highly stable with time and temperature.
A common linear gate establishes the time window during which the analog inputs ore active. This input is operated by standard NIM level signals from 10 to 200 nanoseconds in duration. The Model 2248 offers o number of convenient and flexible features. The Model 2248 represents a very substantial advance in fast pulse ADC capability. In high energy physics, it will permit the use of ADC's for both measurement and monitoring purposes to an extent not previously practical, since for the first time the ADC cost becomes low compared to the existing experimental per-channel investment in the counter assembly and associated electronics and hardware.
