Channel 1 Overlaid Trace Data (TEDS)

The Trace > Data > Channel 1 Overlaid menu provides similar choices as the Trace > Data > Channel 1 Subcarr menu, except Channel 1 Overlaid provides choices for time and frequency trace data for all TEDS subcarriers (not individual subcarriers).

Trace

Description

Error Vector Spectrum

Display of the Analysis Subcarriers, (corresponding to your Channel Bandwidth setting), as green vertical lines, with each green vertical line containing all the symbols for a subcarrier. The whole display is overlaid with a white trace showing the average vector error of each subcarrier(LinMag or LogMag only).

Error Vector Time

Error vector time for every subcarrier symbol on a symbol-by-symbol basis (vertical green line), overlaid with a white trace that shows the average error vector time per symbol (LinMag or LogMag only).

IQ Mag Error

IQ magnitude error for every subcarrier symbol on a symbol-by-symbol basis, overlaid with a white trace that shows the average IQ magnitude error per symbol (LinMag or LogMag only).

IQ Meas Time

All subcarrier symbols. In the constellation diagram, the symbols are overlaid on an ideal state pattern with circles for data symbols and cross-marks for sync and pilot symbols.

IQ Phase Error

IQ phase error for every subcarrier symbol on a symbol-by-symbol basis, overlaid with a white trace that shows the average IQ phase error per symbol (LinMag or LogMag only).

IQ Ref Time

Sequence of ideal I and Q states as a composite of all subcarriers.
