Write Cable List File - Opens a Windows standard “Save File” sub-window to
save the Cable List shown in the tab.
Selected Cable Values – Use to enter the “Cable Description” (16 characters

(impedance) and VF (Velocity Factor, aka VP, VoP, or NVP) of a cable
you desire to add or edit on the cable list.
Use Cable from List – Populates the “Selected Cable Values” with highlighted
cable on the list.
Overwrite Cable in List – Replace the highlighted cable on the list with the
“Selected Cable Values” displayed. To add a cable to the list, scroll through the
list to look for “OPEN…Z0 =33 VF=33” or “OPEN n.” These are available cable
memory slots. The latter will be at the bottom of the list and the “n” indicates how
many open slots remain. Total slots for any one list is 64 as that is the maximum
number of Cable List memory slots in the TDR.
CAUTION: There is no “UNDO” for this button. Make sure you no longer
need the cable being overwritten or it is saved on another list on the PC for
later retrieval.
Promote Cable – Moves the highlighted cable on the list up one slot in the order
with each click on this button.
Demote Cable – Moves the highlighted cable on the list down one slot in the
order with each click on this button.
NOTE: Promote and Demote do not delete or add cables only move their position
on the list for faster access to more often used cables in the TDR.
Erase Cable – Deletes the highlighted cable and replaces it with “OPEN Z0 = 33
VF=33” to indicate a user deleted cable slot available for saving a new cable.
