Keysight 200CD Audio Oscillator, 5Hz - 600kHz

The Keysight 200CD provides stable, high quality signals for a wide variety of applications. It features low distortion, excellent flatness and large, well-calibrated dials. Low-impedance operating levels together with superior insulation guarantee peak performance throughout years of trouble free service. This instrument has a wide frequency range and long dial lengths and feature an improved vernier frequency control. Operation is simplified - just three controls are required.


The 200 CD covers the range of 5 Hz to 600 kHz in five overlapping decade bands. Accurate frequency is provided by 112 dial divisions and an effective scale length of 78 inches; a vernier drive allows precise adjustment. It gives a maximum sinewave output of at least 10 V across its rated load of 600Ω and at least 20 V open circuit. Its distortion rating is very low, < 0.2% from 20 Hz to 200kHz. A special feature of the 200CD is that its waveform purity does not depend on load.
