Frame Summary (5G NR/5G-Advanced)

There are two types of traces in the Trace > Data > Demod and MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. menus that display component carrier data: CCn (component carrier is fixed), and Selected Display CC (component carrier is dynamically selected using the Display parameter). See About Per-Carrier Trace Types for more information.

The Frame Summary trace shows the reference component carrier's 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., power, modulation format, number of resource blocks occupied and RNTI for the channels that are present in the Measurement Interval.

Frame Summary is a type of Matrix Table that provides sortable rows by column, selectable column visibility, and copy/paste and export functionality to share rows of content or complete tables to applications like email, text editing or spreadsheet programs.

Averaging is not applied to the Frame Summary trace.

Trace Color coding Scheme

A multi-color coding scheme is used to make it easy to visually identify common symbols, subcarriers, and data results within various OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. Traces. This makes cross trace data comparisons and analysis easier to accomplish. Different colors are assigned to symbols representing elements including: PSS/SSS/PBCH/PBCH_DMRS/PDSCH/PDSCH_DMRS/PUSCH/PUSCH_DMRS/PUCCH/PUCCH_DMRS. Some common color scheme Traces include: Error Vector Spectrum, Error Vector Time, OFDM Meas, Frame Summary and Slot Summary trace data.

The 5G NR color scheme has been simplified to help make visual sense of a complex standard. The default color assignment for 5G NR follows these general guidelines:

DMRS and PTRS signals
- PTRS and DMRS signals generally are generally assigned cooler colors (greens, blues).
- All DMRS signals share a common color. You can distinguish between DMRS signals using markers, but each DMRS is also visually distinguished by the physical channel in which it is located.
- All PTRS signals share a common color. You can distinguish between PTRS signals using markers, but each PTRS is also visually distinguished by the physical channel in which it is located.
Physical channels (PDCCH, PDSCH, PUCCH, PUSCH, etc.)
- Physical channels are generally assigned warmer colors (yellows, oranges, reds)
- Each physical channel type has an assigned group of colors. For channel collections (multiple channels of the same type), the display will rotate through a group of three similar but distinct colors to distinguish between each channel in the collection. For example, if a signal contains 6 PDSCHs (PDSCH0-5), PDSCH0, PDSCH1 and PDSCH2 will each have similar but uniquely different color assignments. The same colors will be repeated for PDSCH3, PDSCH4 and PDSCH5.

You can also customize and re-assign Trace colors schemes, see the Display Preferences Color tab (click Utilities > Display Preferences > Color tab and select a new color for the active Mod Type element).
