The 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.
||5 Hz to 600 kHz (5 bands)
|Flatness (1 kHz, ref.):
||(600 ohm load) 10 V RMS (> 160 mW; (open circuit) 20 V RMS
||(5Hz to 20Hz) <0.5%; (20Hz to 200kHz) <0.2%; (200kHz to 600kHz) <0.5%
|Hum and noise voltage:
||<0.1% of rated output
||<0.1% at lower frequencies approximately 1% at higher frequencies
