Abstract : The system described is a four-channel recorder system where vibration amplitudes from four selected positions can be compared to each other at any vibration frequency between 10 and 2000 cycles per second. The data is presented as four continuous records of amplitude against a frequency mark on the edge of the record which is coded against a printed tape record of frequency. The system is composed of commercially available equipment and has an overall calibrated accuracy of plus or minus 10%. (Author)
