ModAcc

Specifies whether to enable the traces to be stored and retrieved after performing the ModAcc measurement.

Specifies the method used for the channel estimation for the ModAcc measurement. The measurement ignores this attribute, when you set the RFMXLTE_ATTR_LINK_DIRECTION attribute to Downlink.

Specifies whether the same Reference Clock is used for the local oscillator and the digital-to-analog converter in the transmitter. When the same Reference Clock is used, the carrier frequency offset is proportional to Sample Clock error.

Specifies the units of the EVM results.

Specifies whether to exclude some portion of the slots when calculating the EVM. This attribute is valid only when there is a power change at the slot boundary. Refer to section 6.5.2.1A of the 3GPP TS 36.521-1 specification for more information about exclusion.

Specifies the FFT window length (W). This value is expressed as a percentage of the cyclic prefix length. This attribute is used when you set the RFMXLTE_ATTR_MODACC_FFT_WINDOW_TYPE attribute to 3GPP, where it is needed to calculate the EVM using two different FFT window positions, Delta_C-W/2, and Delta_C+W/2. Refer to the Annexe E.3.2 of 3GPP 36.521 specification for more information.

Specifies the position of the FFT window used to calculate the EVM. The offset is expressed as a percentage of the cyclic prefix length. If you set this attribute to 0, the EVM window starts at the end of cyclic prefix. If you set this attribute to 100, the EVM window starts at the beginning of cyclic prefix.

Specifies the FFT window type used for the EVM calculation for the ModAcc measurement.

Specifies the operation mode of frequency error estimation.

Specifies the in-band emissions mask type to be used for measuring in-band emission margin (dB) and subblock in-Band emission margin (dB) results.

Specifies whether to enable the ModAcc measurement.

Specifies the number of slots to be measured. This value is expressed in slots. For NB-IoT a measurement length of 20 slots is recommended.

Specifies the measurement offset to skip from the synchronization boundary. The synchronization boundary is specified by the RFMXLTE_ATTR_MODACC_SYNCHRONIZATION_MODE attribute. This value is expressed in slots.

Specifies whether to use a filter to suppress the interference from out of band emissions into the carriers being measured.

Specifies the time synchronization mode used in uplink in the case of carrier aggregation.

Specifies the maximum number of threads used for parallelism for the ModAcc 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.

Specifies whether phase tracking is enabled.

Specifies the interval used for Pre-FFT Error Estimation.

Specifies the frequency ranges at which to measure spectral flatness. The measurement ignores this attribute, when you set the RFMXLTE_ATTR_LINK_DIRECTION attribute to Downlink.

Specifies whether the spectrum of the measured signal is inverted. The inversion happens when the I and the Q components of the baseband complex signal are swapped.

Specifies whether to estimate symbol clock error.

Specifies whether the measurement is performed from the frame or the slot boundary.

Specifies whether timing tracking is enabled.
