Menu Selection
Purpose/Action
Resolution
Sets TDR trace horizontal sampling resolution (in
picoseconds):
Normal............................
A setting suitable for connector level detail for each
of the cable length modes. Short is nominally 5.32 ps
(< 1 mm). Medium is nominally 17.5 ps (~2 mm).
Long is nominally 49.6 ps (~1/2 inch). Extra Long is
nominally 381 ps (~2 inches). The actual setting is
dependent on horizontal scale, but will be at least as
good as the nominal value. If the user adjusts the
Horizontal Scale
to zoom in to a very short section of
cable, the resolution setting will automatically adjust
to a finer scale. Multiple measurements may map to
a single horizontal offset on the display. This allows
you to easily see flaws in the cable or connectors
even when looking at long sections (see Figure 3.10).
Screen............................
Screen resolution (1 sample/pixel) varies
dynamically with the current horizontal scale.
Fixed.............................
Allows user to set a specific value no matter the
cable length setting.
File (Load/Save)
Calls up the
FILE
button menu. Use it to add,
select, or delete an entry from the cable type, user
configuration, and/or cable record libraries.
