We report on the prototype of a new digital multi-time-interval analyzer (MTIA-1) based on a counter/memory architecture. The occurrence of multiple events with respect to a common start can be determined with a timing resolution of 4 ns. Incoming standard TTL or ECL pulses are processed and stored immediately after their detection in a 4096×16 Bit RAM. By virtue of this real-time histogramming concept, data acquisition does not have to be interrupted during signal processing. The maximum repetition rate of events to be processed in real time can be in excess of 20 MHz. The MTIA-1 is designed for repetitive timing applications where multiple time intervals have to be processed with very high speed. The analyzer accepts standard TTL or ECL pulses and has a maximum measurement range of 4096 channels. After the end of an individual multi time interval measurement no additional time consuming postprocessing is needed for data transfer or data analysis. The article gives an overview of the structure of the analyzer and its principle of operation. We further present an example for an application where the MTIA-1 is used in fiberoptic distributed temperature sensing.
