Viewing Spectral Flatness Measurement Results

Measurement results available include a graphical window and a text window.
The graphic window shows three traces: Upper Limit trace, Lower Limit trace
and Flatness trace. Limit traces will not include the unused subcarriers, like #0
subcarrier in 802.11a. Flatness trace will be combined with some blue points
which indicate the position of subcarriers. If all the blue points fall between the
limit lines, the measurement will pass.
The text window shows Radio Format Info, Max Point to Upper Limit and Min
Point to Lower Limit for Section 1 and Section 2.
For more information on what these data are, see the N9077A & W9077A
