Press the ∇ or  arrow key to view the previous or next test results screen.

Press the ESCAPE key to return to the AUTOTEST RESULTS screen.

Note: For diagnostic purposes, you can run NEXT continuously by pressing the Measure Cable Performance key and selecting NEXT.

NEXT Detail

To display this screen, press Detail (F1) from the NEXT screen. This screen displays the frequency sweep range and the worst case NEXT for each pair.

Press Graph (F1) to enter graphing mode. Graph (F1) is available when Save Sweep Data has been selected in the AUTOTEST SETUP, or when NEXT results are viewed immediately after running the test.

Press Pair (F3) to toggle through the available pair combinations.

When using the 2-Way Injector+ (or the 2-Way Injector), press F4 to toggle between NEXT results for the Scanner (Penta) or Injector (Inj) end of the link.

Press the ESCAPE key to return to the NEXT screen.

NEXT Graph

To display this screen, press Detail (F1) from the NEXT screen, then press Graph (F1). This screen displays the NEXT graph for the indicated pair combination.

The top line of the screen displays the worst case NEXT and the frequency at which it occurred.

When using the 2-Way Injector+ (or the 2-Way Injector), the second line of the screen indicates if NEXT is being reported for the Scanner (Penta) or Injector (Inj) end of the link.

Press Zoom (F1) to magnify the area of the graph around the cursor. The Zoom key can display 1x, 2x, 5x or 10x magnification.

Press Print (F2) to print the NEXT graph.

Press the ESCAPE key to return to the NEXT DETAIL screen.

Attenuation

The Attenuation function measures signal loss in a cable as a function of frequency. This measurement is a very important cable certification parameter. Your Scanner measures cable attenuation using the one way method as specified by IEEE and EIA.

The one way Attenuation measurement requires that a signal be injected at one end of the cable and measured at the other end to determine cable loss. The Injector acts as the far end signal generator and the Scanner NEXT receiver measures the received signal.
