Signal Generator - Phonic PAA6 Manual Del Usuario

SIGNAL GENERATOR

The signal generator can be accessed through every function of the PAA6. There are seven built-in
signals, each with their own adjustable properties. All generated signals can have their output level
adjusted between -40 dBu and +4 dBu. All signals – except the sweep signal – can also have their
gate time adjusted, where users can select a time up to 10 seconds for the signal to run, at which time
the signal will turn off.
Sweep: The sweep signal consists of a sine wave with an ever-changing frequency. The frequencies
can be user-defined, with 1/6, 1/3, 2/3 and 1 octave intervals selectable by the user. Alternatively, users
can choose 'Select' and adjust the sweep range manual. Once users choose 'Select', the Sweep start
and Sweep stop fields will become active and users can select the start frequency (between 20Hz and
20 kHz) and stop frequency (between 20 Hz and 20 kHz). Users can opt to have a continuous sweep
tone, where the signal generator will run through the entire audio spectrum selected, then stop again.
Alternatively, users can opt for the tone to repeat itself anywhere between 1 and 10 times before it
turns off (figure 66).
Sine: Used for a variety of purposes. A 1 kHz sine wave is perhaps the most commonly used sine wave.
However, users can adjust the PAA6's sine wave to a number of frequencies between 20 Hz and 20 kHz
(figure 67).
