NOTE: The Rx test has two test reports (Test Signal Amplitude and Frequency) which are listed in the
Reports window on the right. By default, the Test Signal Amplitude report is displayed in the
Reports window below (Figure 7-34 "View Test Log - Rx Test Signal Amplitude" on page 7-59).
NOTE: Left and right arrows provided in the View Report window enable scrolling between the different
channels.

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 7-34 "View Test Log - Rx Test Signal Amplitude" on page 7-59.
