Description: Return the average of the RMS phase error values computed on each 50 us block of EDR portion of the EDR packet. When you set the RFMXBT_ATTR_MODACC_AVERAGING_ENABLED attribute to RFMXBT_VAL_MODACC_AVERAGING_ENABLED_TRUE, it returns the mean of the average RMS phase error values computed for each averaging count. This value is expressed in degrees.

You do not need to use a selector string to read this result for the default signal and result instance. Refer to the Selector Strings topic for information about the string syntax for named signals and results.

RFMXBT_ATTR_MODACC_RESULTS_PEAK_RMS_PHASE_ERROR_MAXIMUM

Data Type: float64
Access: read only
Functions: RFmxBT_GetAttributeF64
Description: Return the peak of the RMS phase error values computed on each 50 us block of EDR portion of the EDR packet. When you set the RFMXBT_ATTR_MODACC_AVERAGING_ENABLED attribute to RFMXBT_VAL_MODACC_AVERAGING_ENABLED_TRUE, it returns the maximum of the peak RMS phase error values computed for each averaging count. This value is expressed in degrees.

You do not need to use a selector string to read this result for the default signal and result instance. Refer to the Selector Strings topic for information about the string syntax for named signals and results.

RFMXBT_ATTR_MODACC_RESULTS_IQ_ORIGIN_OFFSET_MEAN

Data Type: float64
Access: read only
Functions: RFmxBT_GetAttributeF64
Description: Returns the I/Q origin offset estimated over the EDR portion of the EDR packets. This value is expressed in dB. When you set the RFMXBT_ATTR_MODACC_AVERAGING_ENABLED attribute to RFMXBT_VAL_MODACC_AVERAGING_ENABLED_TRUE, it returns the mean of the I/Q origin offset values computed for each averaging count.
