Abstract
The system design and system accuracy of an Audio Voltage Calibrating Standard is described and discussed. The unit provides a regulated setable sine-wave output voltage of 0.1000 to 1,099.9 volts in 4-decade ranges from 50 cps (cycles per second) to 10 kc (kilocycles). The rated accuracy is ±0.05% of indicated value at 10% to 100% of each decade range from 50 cps to 2,500 cps. The accuracy reduces to ±0.25% at 10 kc in the frequency range of 2,500 cps to 10 kc. The output current capability varies from 5 amperes at the low voltages to 40 milliamperes at the highest output voltage.
