Sample a Varying Analog Signal (0 to 10 kc)
With a Trigger Pulse (0 to 50 kc)
Convert it to Digital Signals for Storage, Display and Data Reduction
WITH THE NEW TMC 401M PULSE HEIGHT ANALYZER The Mode! 401M pulse analysis system permits on-line sampling of varying analog signals where immediate analysis of the information is required in a digital form. Measurements on radar return signals to determine charged particle densities in space and Mossbauer effect experiments are typical of the many applications requiring this type of analog-to-digital conversion. Operation The 401 M is provided with two inputs. A varying analog signal is applied to one input. The second input accepts pulses which determine the sampling rate. These pulses allow counts, proportional to the instantaneous amplitude of the analog signal, to be stored in a corresponding channel in the magnetic core memory. These counts may then be displayed for visual study or read out through a variety of data handling units for a permanent record. Optional data reduction units permit scaling, addition, subtraction and integration of information stored in different portions of the memory.
