ADSL TESTER D2061 

                                                                                        USER’S MANUAL 

 

The test allows to send on line a single tone or to carry out a scansion of the band 
both, in manual and automatic mode. 

The level value is definable by the user as well as the scanning time and the delta 
frequency in 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.  

Define the following parameters for a Tone Generator test: 

Called number: Enter the phone number of the called party. 

Freq start (Hz): Insert the initial frequency value (range from 300 to 3400). If the 
value is different from Freq.stop, the device performs a scansion of frequencies 
included between the two values. 

Freq stop (Hz): Insert the final frequency value (range from 300 to 3400). If the value 
is different from Freq.start, the device performs a scansion of frequencies included 
between the two values. 

∆F (Hz): Define Delta value (gap) to use to pass from a tone frequency to another in 
manual mode.  

Level (dBm): Choose the width for the sinusoidal tone generated. 

Sweep Time: Select the waiting time between one tone and the other, sending tones 
may be carried out manually by selecting ‘Manual’. Only if Freq.start and Freq.stop 
are different.
