Return the single value results of the "EVM vs Preamble" and "Power vs Preamble"
views, for a selected preamble.
See also chapter 4.2.9.3, "Detailed Views: EVM vs Preamble, Power vs Preamble" ,
on page 751.
The number to the left of each result parameter is provided for easy identification of the
parameter position within the result array.
Suffix:
<Number>
.
1..16
Number of the preamble for which the results shall be queried
