Frame Summary (5G NR)

There are two types of traces in the Trace > Data > Demod and MIMO 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, 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.

Name Physical Channel User Part Layer EVM (%rms) SINR (dB) Power per RE (dBm) Modulation Num. of RBs RNTI BWP ID PID Time Advance (ns)

Name is a unique, but arbitrary reference to a Frame Summary row that is derived from Physical Channel, User, Part and Layer as applicable. Possible names include:


  • CSI-RS
  • CSI-RS_Port
  • PSS
  • SSS
  • PBCH
  • Non alloc


  • PUSCH_Layern
  • Non-alloc

Physical channels include:


(0) PSS

(1) SSS

(2) PBCH





(7) CSI-RS

(8) DC

When there is a single user, the default user number is 0. Rows without user data are denoted with '***'.

Some physical channels have multiple parts. Physical channel parts include:


(0) Data

(1) DMRS

(2) PTRS

Rows without layer data are denoted with '***'.

EVM is the per-layer RMS EVM after demodulation.

The Report EVM in dB parameter affects the units of this data result.


NOTE: When PUCCH0 and PUCCH1 have overlapping resources (see Sequence Cyclic Shift), EVM result will only be shown on PUCCH1, and it will be the composite EVM of both PUCCH0 and PUCCH1.

SINR is the signal-to-noise and interference ratio for the channel.

Power is the per-subcarrier power received at the reference measurement channel, averaged over all the subcarriers belonging to the physical channel.

Mod. Fmt. is the modulation format of the channel.

The modulation format for Non-alloc signals is not shown.










Num. RB shows the number of resource blocks (1 RB x 1 slot) within the Measurement Interval that contain subcarriers belonging to the channel.

Num. RB is not shown for Non-alloc signals.

RNTI shows the Radio Network Temporary Identifier (RNTI)for the channel.

BwpID displays the ID number of the BWP that is associated with the row's physical channel.

PID displays the auto-detected Preamble ID.

PID is only available in PRACH Auto Detection mode. If '***' is displayed, make sure that PRACH Auto Detection is enabled.

Time Advance displays the auto-detected timing offset.

When doing the Time Advance measurement, the assumption is the signal is captured using frame trigger, and the Time Advance is the difference between the actual PRACH Occasion time relative to the frame boundary and the expected PRACH Occasion Time relative to the frame boundary.

Time Advance is only available in PRACH Auto Detection mode. If '***' is displayed, make sure that PRACH Auto Detection is enabled.

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 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:

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).
