Profile Tab (NB-IoT)

The Profile tab allows you to specify user channel allocations as well as specify which channels are shown on traces and used in the 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. and EVM Pk data results on the Error Summary trace.

Uplink

Uplink Channel Mapping Parameters

The Composite Include group box lists the channels in the signal being analyzed. Clearing a channel's check box will remove that channel from calculations and traces, except for Frame Summary, which shows information on all channels.

When Non-alloc is selected, unused subcarriers will be shown on all traces and included in EVM and power calculations. See the Frame Summary Non-Alloc topic and the Composite Include topic for more information on the definition of Non-alloc for different traces.
