The Platform can display two additional results:
•
The gain tilt, that is to say the difference between the max.and min. values of the
peaks of the complete signal spectrum between the cursors.
•
The gain slope measured by a method using a least squares algorithm on all
detected channel using peak power levels or channel power levels.
To display these results above the channels:
1
Press the Advanced button
2
Press Measure A<->B button
3
Select the cursor and set it to the measurement range limits
