Jerrold 601 Sweep Frequency Generator

Barco Library Equipment Archives

Jerrold Models 601 and 602 were portable, wide-band sweep frequency generators for testing and aligning rt circuits in the frequency range from 4 to 225 megacycles in the 1960s.

Model 601 operateed in the range from 12 to 225 me, Model 602 in the range from 4 to 112 me. The frequencies covered by each model were divided into 11 overlapping ranges.

Both models featured a push-pull "Hartley" oscillator swept by a saturable reactor, and controlled by circuitry that leveled the oscillator output to within 1 db over the entire sweep width.
