Error Vector Time (Low | Mid | High Band) (MB-OFDM)

The Low | Mid | High Band Error Vector Time trace shows a series of vertical lines where each line represents a Low | Mid | High Band burst of 122 subcarriers (OFDM Symbols) organized by symbol number on the x-axis. The quantity of vertical bursts corresponds to the settings for Result Length, Measurement Offset, and Measurement Interval (see Lengths, Intervals, and Offsets).

For a composite trace that includes all bands, including the example below, see Comp Error Vector Time. For trace identification, the pilot and guard symbols are colored differently than the data symbols.

Setup Example

Select the Low Band Error Vector Time trace. Let Result Length = 12 | Measurement Offset = 0 | Measurement Interval = 6 | TFC = 1. For these conditions, this trace displays (2) vertical lines for Low Band symbol-times 0 and 3 in sequence Low-Low (TFC Transport Format Combination = 1) with each vertical line representing a burst of 122 subcarriers (OFDM Symbols) -61 to -1 and +1 to +61. For trace identification, the pilot and guard symbols are colored differently than the data symbols. The illustration below shows the (2) burst sequence for this a Low Band example.
