NOTE: The ACW Delay Range Test test has three test reports (Signal Frequency, Signal RMS, and
Signal SNR) which are listed in the Reports window on the right. By default, the Signal
Frequency report is displayed in the Reports window below (
Figure 7-43 "View Test Log - ACW
Delay Range Test - Signal Frequency" on page 7-72 ).
NOTE: Left and right arrows provided in the View Report window enable scrolling between the different
channels.
Left-clicking on a currently-selected channel marks a red square on the report graph, and also evokes
the display of the following information relative to that specific point: Average, Deviation (standard
deviation from the Average), Max, and Min.
The signal should be within the limits marked in the white area (the dotted line represents the Average),
as shown in
Figure 7-43 "View Test Log - ACW Delay Range Test - Signal Frequency" on page 7-72 .
