Managing Elements
When you hover the mouse over any element groups, the application
displays the group details separated by semicolons.
When you hover the mouse over any element with a diagnostic label, the
application displays the description.
Note: It is possible to underestimate the loss or reflectance value if the noise level
is too high (for instance, after a lot of loss on the link, the noise levels
increase). In that case, it is possible for the signal processing algorithms to
detect an element, and to estimate the loss/reflectance values, but since the
measured signal does not completely clear the noise floor, the loss or
reflectance values are likely to be underestimated. If the loss or reflectance
value is underestimated, the value is displayed with a > symbol.
