SHOW REF 

Pressing the function button corresponding to SHOW REF allows a user to 
overlay a REFERENCE MASK over the test result on screen to compare the 
two.  See Section 5.4 for more information about the REFERENCE MASK 
feature. 

 
 
Pressing the 

SAVE / UPLOAD 

button shows a pop-up window where the user is allowed to upload results, 

and save results to internal memory or to external USB memory. 
 

UPLOAD RESULT 

Choosing UPLOAD RESULT from the SAVE / UPLOAD pop-up menu sends 
the result that appears on the CableSHARK screen (current test or recalled 
test) to a PC via a NULL modem cable. The remote control program Visi-
SHARK can be used to capture and analyze the results on a PC. 

 

SAVE TO MEM 

Choosing SAVE TO MEM from the SAVE / UPLOAD pop-up menu invokes 
the SAVE SESSION menu.  From here, the test results can be saved to 
internal non-volatile memory. See Section 5.3 for more information. 

 

SAVE TO USB 

Choosing SAVE TO USB from the SAVE / UPLOAD pop-up menu invokes 
the SAVE SESSION menu.  From here, the test results can be saved to 
external USB memory. See Section 5.3 for more information. 

 
The remainder of the buttons are as follows: 
 

ZOOM IN HORIZ / 
ZOOM OUT HORIZ 

Use these function buttons to zoom IN and OUT based on the horizontal 
graph scale. Please note after the completion of a test, the ZOOM OUT 
HORIZ option will be disable as it is impossible to ZOOM OUT. Press the 
ZOOM IN HORIZ button once or multiple times and the ZOOM OUT HORIZ 
button will appear. Likewise, when the  maximum zoom level is achieved, the 
ZOOM IN HORIZ button will disappear. 
 

TEST SETUP 

Pressing the function button associated with TEST SETUP activates the 
SHDSL Test Setup menu.  Test parameters can be modified and the test can 
be run once again from this screen. 

 

MAIN MENU 

Select MAIN MENU to return to the Main Menu.
