I/Q Error
This view has three windows:
1. Magnitude Error window (upper)
2. Phase Error window (middle)
3. EVM window (lower)
The traces of this view are not averaged, even if the average function is on.
The parameters displayed in these windows differ depending on the setting of Radio Device in the Mode
Setup menu (see
). For details of each view, see:
•
"I/Q Error View (BTS)" on page 2329
•
"I/Q Error View (MS)" on page 2331
