OmniTek OTR 1001 User Guide, v3.1a
S-17
S.5 PQA Charts
This display is the main reporting medium for the PQA measurements made by the OTR.
Figure S-14:
Example PQA Charts display.
The main section of the display comprises graphs of the various parameters that are calculated.
Which graphs are displayed is determined by the options selected in the Properties control (see
below). The Properties control may also be used to set the style of the graphs (line or solid), the
layout of the graphs (stacked, parade or overlay) and the colours used to display the graphs.
Each graph is calibrated between 0 to 100. In each case, 100 is good, and 0 is bad. Somewhere in-
between will be the Error Level that marks the threshold between acceptable and unacceptable
values, the location of which is set on the Video Config page of the Config window (see Section T.2)
and indicated by a broken line on the display
.
The threshold to set should be determined by the user,
based on their experience of using the product. The horizontal axis is also common to each graph,
and shows the number of frames being displayed. The default is to display the most recent 500
frames (with the most recent frame labelled as frame number 500 and located at the rightmost edge
of the graph), but this ‘Analysis Duration’ can be changed on the Video Config page.
The yellow line marks the current cursor position. The pair of numbers shown above this line
indicate the current cursor position and the value of the relevant parameter at that position. The
cursor position is initially placed at the right-most point of the graph (making the value shown
that for the newest frame of data) but it can be moved to other locations by clicking on the
display. (The cursor moves to the same position in all the graphs to show you a complete set of
data at the selected point.)
Options on the Button Bar (and in the Properties control) allow you to both clear the current data
and to pause collection of PQA data, in essence freezing the display.
