Signal shape<br />
With the signal shape selector buttons the signal type can be set. Possible signals are:<br />
S<strong>in</strong>e<br />
Triangle<br />
Square<br />
DC<br />
White noise<br />
File<br />
a s<strong>in</strong>e wave is generated<br />
a triangle wave is generated<br />
a square wave is generated<br />
a constant DC level is generated<br />
a white noise is generated<br />
a signal from a file is generated<br />
The signal type File is discussed later.<br />
Frequency<br />
In the Frequency box all controls for adjust<strong>in</strong>g the signal frequency are located. Seven decade buttons set a frequency<br />
range <strong>in</strong> which the frequency can be set us<strong>in</strong>g the slider. Each range runs from 0.2 to 2 times the value on the button.<br />
When the signal shape is set to DC, the frequency adjustment is disabled.<br />
Symmetry<br />
The symmetry of a signal <strong>in</strong>dicates the relation between the length of the positive part of the period to the total length<br />
of the period. A symmetry of 50% means that the positive part is exactly half of the total period.<br />
Us<strong>in</strong>g the slider <strong>in</strong> the Symmetry box, the symmetry can be adjusted between 1% and 99%. The Mid button sets the<br />
symmetry to 50%, the centre position.<br />
When the signal shape is set to DC or White noise, the symmetry adjustment is disabled.<br />
