Cable impedance
To measure the characteristic impedance,
use a piece of an open circuited cable:
a half of a meter (or a foot) or longer
should be fine. Press
(OK) to start.
Next, the far end of the cable should
be short circuited. Press
(OK) to
continue.
There are several reasons why the
resulting chart does not look smooth,
so we need to use
(Left) and
(Right) cursor keys to find the location
where the impedance is stable. The result
is shown at the bottom left corner of the
screen.
Use
+
(Up) and
+
(Down) key combinations to change the
scale, if needed.
