Monitor; a Low Cost, Versatile Data Acquisition Program
For research purposes it is often necessary to collect analog data. Until recently it was customary to view this analog data on an oscilloscope, and to store it on an analog tape recorder, thus introducing with the disadvantage of extra noise and a limited dynamic range. Interesting parts of the data could be played back for reviewing and production of a hard copy with a chart recorder. After this the tedious job of working out the collected data started. Time intervals and amplitudes were measured with a ruler and recorded manually on an other piece of paper. From this data graphs were plotted manually and statistics were calculated.
