This manual provides operating instructions, specifications, and maintenance information for the Hewlett-Packard Model 200A Audio Oscillator.
The Hewlett-Packard Model 200A Audio Oscillator is a general-purpose instrument that uses a resistance-tuned circuit to generate alternating current voltages from 35 to 35,000 cycles/sec. It is designed for amplifier testing, audio response tests, resonance tests, and as a voltage source for bridge measurements. The unit includes an oscillator section, an amplifier section, and a power supply, utilizing vacuum tubes for signal generation and amplification.
