Two independent voltage-controlled oscillators. Each has one processing input, a frequency modulation input and a 1V/oct input. Waveshapes, as well as frequency, can be voltage controlled. Model 258 oscillators feature low sine wave harmonic content, negligible settling error, and high short and long-term stability, even with rapidly changing ambient temperatures.

• • 1V/oct is the octave tracking trimmer and is set at the factory using high precision instruments
  • SHAPE is the trimmer that set the sine wave, for the lower harmonic content of the sine wave
  • VC WAVE SHAPE sets the response of the waveshaper to the incoming control voltage. Both SHAPE and VC WAVE SHAPE trimmers are used to adjust the sine wave purity
