option)
By the use of this test the device works as generator of sinusoidal signals with phonic
band frequency included between 300 - 3400 Hz.

Used in couple with a remote receiver it is possible to check for instance, the correct
opening and transparency of the audio channel in case of conversion into digital
lines, or it is possible to check the quality of the band considering parameters such as
distortion and line attenuation.
