Connect, protect, and deliver seamless experiences. The Model 200AB introduced advances in electrical and industrial design, all without an increase in price. An audio oscillator is an instrument that generates one pure tone or frequency at a time.

The 200AB was used for amplifier testing, as a bridge voltage source, for testing transmitter modulator response, modulating signal generators, syncing pulse generators, making loudspeaker resonance tests and powering mechanical systems.

The Hewlett-Packard HP-200AB audio generator will generate sine waves from 20 Hz to 40 KHz. Like the other HP audio generators, the circuit uses the famous light-bulb-stabilized Wien bridge oscillator patented by William Hewlett in the late 1930's.

The Model 200AB Audio Oscillator is designed for general purpose audio testing and measurements. The resistance-capacity oscillator used in this in- strument will retain its high degree of accuracy for long periods of time with no adjustment. The push- pull output amplifier used in the Model 200AB has

new -hp- Model 200AB. It replaces the older Models 200A and 200B which have been dis- continued. The frequency range of the new 200AB is 20 cps to 40 kc. This contrasts with a range for the former 200A of 35 cps to 35 kc and for the former 200B of 20 cps to 20 kc. The 200AB delivers a maximum of at least 24.5 volts across loads of 600 or more ohms.

The Model 200AB introduced advances in electrical and industrial design, all without an increase in price. Take a virtual tour of this product, see close-up images and read about its history.

Item: 1950'S Model 200AB Wide Range Oscillator / Audio Generator / Audio Amp. Details: Wien Bridge Type Oscillator, 20 Hz to 40 KHz Sine Wave Generator. WHEN I POWER THIS ON I CAN HEAR THE ELECTRONICS WARM UP AND HUM SOUND CHANGES AS I ADJUST THE RANGE AND AMPLITUDE.

One of the improvements was a large, six-inch tuning dial. The 200CD was used for testing servo and vibration systems, medical and geophysical equipment, audio amplifiers, sonar and supersonic apparatus, carrier telephone systems and video frequency circuits. Frequency Range: 5Hz to 600kHz in five ranges.

2012年12月3日 · Electrically, there's not a whole lot of difference between the octal tubes and the 7 pin miniature replacements in the 200AB circuit. The 200AB is a real keeper. and can be used as an audio amp of obviously very wide frequency range with that serious inverse feedback output transformer. http://www.hparchive.com/Manuals/HP-200 ...
