Results area Results area (graph)
The results area utilizes most of the screen and provides you with the
measurement results. A grid of ten vertical and eight horizontal rows
eases readability of results from the axes. There may be one or two
graphs, depending on the number of traces selected.
Horizontal axis
The horizontal axis is the frequency axis for the spectral components.
The zero span mode is an exception, as the horizontal axis is the time
axis in this case. Another exception is the Distance to Fault mode, as in
this mode this axis displays the distance in metres or feet depending
on the unit you select. The values of the frequencies at both ends of the
scale are indicated (start and stop frequencies).
Vertical axis
The vertical axis reflects the RF power. Depending on your choice of
the level unit, the RF power is indicated in dBm, dBV, dBmV, or dBμV.
The top end of the power scale is called the reference level.
Symbols (icons)
Apart from the results graph itself, several icons are available to indi-
cate the status of the 9102 as follows:

The 9102 is taking its operating current from the bat-
tery. The colored area marks how much of the capac-
ity is still available.
For 30% or more, the area is indicated in yellow; from
10% to 30%, the area is shown in red, and in white for
less than 10%. The 9102 sounds a double beep when
the capacity goes below 30% of its nominal value and
two double beeps below 10%.
