| Description: | Specifies whether to enable the 20dBBandwidth measurement specified in section 4.5.5 of the Bluetooth Test Specification v5.1.0. The measurement uses a span of 3 MHz internally. This measurement is valid only for basic rate (BR) packets. You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals. The default value is RFMXBT_VAL_FALSE.

| Description: | Specifies whether to enable averaging for the 20dBBandwidth measurement. You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals. The default value is RFMXBT_VAL_20DB_BANDWIDTH_AVERAGING_ENABLED_FALSE. Get Function: RFmxBT_20dBBandwidthGetAveragingEnabled Set Function: RFmxBT_20dBBandwidthSetAveragingEnabled |
| Values: | |
|---|---|
| RFMXBT_VAL_20DB_BANDWIDTH_AVERAGING_ENABLED_FALSE (0) | The measurement is performed on a single acquisition. |
| RFMXBT_VAL_20DB_BANDWIDTH_AVERAGING_ENABLED_TRUE (1) | The 20dBBandwidth measurement uses the RFMXBT_ATTR_20DB_BANDWIDTH_AVERAGING_COUNT attribute as the number of acquisitions over which the 20dBBandwidth measurement is averaged. |

| Functions: | RFmxBT_SetAttributeI32 RFmxBT_GetAttributeI32 |
| Description: | Specifies the number of acquisitions used for averaging when you set the RFMXBT_ATTR_20DB_BANDWIDTH_AVERAGING_ENABLED attribute to RFMXBT_VAL_20DB_BANDWIDTH_AVERAGING_ENABLED_TRUE. You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals. The default value is 10.

| Description: | Specifies whether to enable all the traces for the 20dBBandwidth measurement. You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals. The default value is RFMXBT_VAL_FALSE.

| Description: | Specifies the maximum number of threads used for parallelism for the 20dB bandwidth measurement. The number of threads can range from 1 to the number of physical cores. The number of threads you set may not be used in calculations. The actual number of threads used depends on the problem size, system resources, data availability, and other considerations. You do not need to use a selector string to configure or read this attribute for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals. The default value is 1.
