Wobbulator

A wobbulator is an electronic device primarily used for the alignment of receiver or transmitter intermediate frequency strips. It is usually used in conjunction with an oscilloscope, to enable a visual representation of a receivers passband to be seen, hence, simplifying alignment; it was used to tune early consumer AM radios. The term "wobbulator" is a portmanteau of wobble and oscillator. A "wobbulator" is a generic term for the swept-output RF oscillator described above, a frequency-modulated oscillator, also called a "sweep generator" by most professional electronics engineers and technicians. A wobulator was used in some old microwave signal generators to create what amounted to frequency modulation. It physically altered the size ot the klystron cavity, therefore, changing the frequency. When capitalized "Wobbulator" refers to the trade name of a specific brand of RF/IF alignment generator. The Wobbulator was made by a company known as "TIC" although some units branded Allen B. Du Mont Laboratories" and "Stromberg-Carlson" are rumored to exist. These were apparently made under some form of license and branded with the name of the licensee, much as Radio Corporation of America through subsidiary Hazeltine Corp., licensed its KCS-20A television chassis design to other television manufacturers for production under their brand names. The Wobbulator generator, designated model 1200A, combined sweep and marker functions into a single, self-contained, pushbutton-controlled device which, when connected to an oscilloscope and television receiver under test, would display a representation of the receiver's RF/IF response curves with "markers" defining critical frequency reference points as a response curve on the oscilloscope screen. Such an amplitude-versus-frequency graph is also often referred to as a Bode plot or Bode graph.
