Model 158

Dual Sine-Sawtooth Oscillator

Two independent oscillators in one unit. Frequencies are continuously variable from 5 cps to 20 kc and may be controlled internally or with externally applied control voltages. Waveshape is continuously adjustable from sine to sawtooth; oscillators may be wideband frequency modulated.

There are two versions of this module. Rev. A is all discrete transistor. Rev B. uses a transistor oven to add temperature stability.
