• Anotaciones

• The Model 202D Audio Oscillator is a general purpose oscillator which uses the resistance-tuned circuit to generate alternating current voltages from 2 to 70,000 cycles/sec. This audio oscillator provides a source of voltage for amplifier testing, audio response of transmitters, loud speaker resonance tests, and a voltage source for bridge measurements. It is particularly useful where low frequencies are involved, as in mechanical vibration problems.
