CALIBRATION AND NECESSARY EQUIPMENT
The SORS is factory calibrated and use of the following procedures is not
required in daily operation. The following equipment is required to calibrate the
Stereo Optical Recorder: An audio signal source whose distortion is less than
0.05%; a digital voltmeter; a distortion analyzer; oscilloscope and frequency
counter. The distortion analyzer should be band limited to 20kHz at its input to
eliminate high frequency clock signal feed through. (Note: All measurements
made during the calibration of the unit are made between the stated test point
and the system ground. A convenient ground is provided as a loop of bare wire
labeled GND on the PC board.)
