CAMAC - 3664 Time Interval Counter View Datasheet Request Ordering Information     ABOUT 3664 The Model 3664 is a single-width CAMAC module containing six channels of time interval counters. Data from the module can be used to represent the time elapsed between a Start and a Stop pulse, or it can be used to determine the average frequency of an input pulse train. Each channel contains a 24-bit time interval accumulator and a 16-bit, presettable input pulse counter. Latches are provided to hold the count, thereby eliminating the need to continuously rewrite the pulse counters. Time intervals are derived from a common, crystal-controlled clock on the module having Dataway selectable frequencies ranging from one hertz to ten megahertz in decade steps. Once the timing cyclehas been initiated (via front-panel input signal or Dataway command), the accumulators record timing information until the preset number of input pulses has been received by the 3664. The overflow from each channel's input pulse counter or time interval counter stops the timing sequence and sets a LAM Status bit for that channel.
