Figure 3-6: Error Vector Magnitude view
●
Upper diagram
The bar graph shows the EVM for each SC-FDMA symbol in the measured slot.
The symbols are numbered from 0 to 6, with the reference symbol labeled 3.
Each value is an RMS value or a peak value over all modulation symbols in the
SC-FDMA symbol. The title above the bar graph indicates whether RMS or peak
values are currently displayed. To switch between RMS and peak values, use the
softkey - hotkey combination "Display" - "Select Trace".
●
Lower diagram
The lower diagram shows the EVM for all modulation symbols in the measured
slot. The results in the upper diagram are calculated from these data.
For a description of the statistical overview, see Chapter 3.3.2.10, "View TX Measure-
ment" , on page 223.
For the parameters at the bottom, see Chapter 3.3.2.13, "Common View Elements" ,
on page 225.
For query of the diagram contents via remote control, see Chapter 3.5.3.9, "EVM
Results (Traces)" , on page 296.
3.3.2.3 Views Magnitude Error, Phase Error
Both views show a diagram and a statistical overview of results per slot.
