time study over a longer period you may select a window that
shows up to the last
24 Hours
.
Rolling your mouse over this screen will drag a cursor over the
plot, the arrow and vertical white line just to the right of center
in the example screenshot. The numerical values directly below
the plot show the multiple parameter levels at the cursor posi-
tion, and the current incoming value when the cursor is not on
the screen. With
Time Span:
set at an hour or more, actual clock
time of the event is shown bedside the cursor.
Modulation
The Modulation screen used in the example above displays
both the (integrated) instantaneous peak value of carrier devia-
tion in yellow ( Mod %: ), and a held-peak ( Mod Peak %: ) value in
green. (The
Mod Peak %:
reading is also the value used for the
overmodulation alarm.)
RF Metrics
Reception metrics re-
ally ought to be rock-
solid. The station
shown here does ex-
hibit slight variations
in
RSSI
and
RF SNR
,
with numerical values
shown below the plot
for the current mo-
ment. Again, a white-
line cursor allows you
to read the exact val-
ues of these parame-
ters at any point with-
in the displayed time-
frame.
Audio History
Left- and right-channel
program audio levels
are shown here in 2
colors. These are qua-
si-peak readings that
will give a good indica-
tion of program dy-
namics. In this exam-
ple, the pop-music
station went into a
commercial cluster a
little over 20 seconds
before the screenshot
was taken; note the
change in program dy-
namics.
