ADDAC701 Calibration Guide

Sine Calibration

CALIBRATING THE SINE SYMMETRY

1. Connect the "Sine Output" to an oscilloscope

2. The "Sine Symmetry" trimmer acts like an Offset for the

Sine center position adjust it until you have a symetrical

shape between the positive and negative side.

CALIBRATING THE SINE SHAPE

3. The "Sine Shape" trimmer acts like a a linear to log/exp

converter from the triangle waveform, too much and you

get something close to a square wave, too little becomes

closer to the initial triangle. As you tune it closer to the

typical sine waveform you'll hear the undesired harmonics

disappearing.

While all other instructions in these callibration instruc-

tions have very precise settings, the Sine Shape can be

calibrated to the user's prefered timbre, so look at the sine

on the oscilloscope make sure it's close to perfect and

leave it at that sweet spot where your ears tell you to.
