Q141 Oscillator Aid 

Use the Q141 aid module next to your Q106 oscillator for additional functionality including a soft sync input 
with amount control, waveform selector, amplitude adjustment, and inverted outputs.  
 

Tracking Accuracy 

Tracking accuracy determines how closely your oscillators track the keyboard.  Human hearing is very 
sensitive to pitch and some people can discern differences as low as .2%. Tracking is most important on 
frequencies from 32hz to 4096hz (7 octaves). We think this is the most important parameter of an oscilla-
tor.  
 
Test Equipment Used (all have recent calibration): 
   HP 5335a 9 Digit Frequency Counter 
   Fluke 3330b Voltage Calibrator
