Module 80-2

 Voltage Controlled Oscillator

The 80-2 VCO is based on the CEM 3340 IC and has a standard 1v/octave response. The tracking is most accurate in the range 5Hz to 10kHz, however the unit will function from as low as 0.1Hz to 50Khz. The 3340 features an inbuilt Tempco generator to minimise thermally induced frequency drift. This is not perfect by any means, so expect to retune regularly!
