/ˈwɑbjəˌleɪdər/

Forms: 1900s– wobbulator, 1900s– wobulator.

Etymology: < wobb- (in wobble n. or wobble v.) + -ulator (in modulator n.).

Electronics. Now chiefly historical.

A device for producing a signal whose frequency varies continuously between two limits, used typically to align electronic equipment such as a radio receiver or to test the frequency response of a circuit; also called sweep generator.

1933 QST (Amer. Radio Relay League) May 21/1 To those already familiar with the ‘wobbulator’ type of transmitter on 56 mc., the transition to a stable transmitter should be easy.

1958 Electronic Engin. 30 541 A wobulator for amplitude testing often gives errors because of unwanted signal amplitude variations.

1977 S. W. Amos Radio, TV & Audio Techn. Ref. Bk. xxxii. 9 Alignment should not be attempted on any u.h.f. tuner without the use of a u.h.f. wobbulator.

2005 M. Brend Strange Sounds 75/1 The rudimentary sound-generating and recording equipment..comprised of little more than..a white noise generator, and a low frequency oscillator dubbed the wobbulator.
