OFDM Err Vect Spectrum (6GR)
The traces in the CCn and Selected Display CC menus are identical and show the same CC0 information.
The trace shows per-subcarrier EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. across the channel bandwidth, plus an overlaid trace of the RMS average subcarrier EVM. Unused subcarriers are blanked and not included in the analysis. This is the EVM-versus-frequency view — useful for spotting subcarrier-localized impairments (for example, a specific resource block or an edge-of-band problem) that a single aggregate EVM number would hide.
