Specifies whether RFmx optimizes the acquisition bandwidth. This may cause acquisition center frequency or local oscillator (LO) to be placed at different position than you configured.

Description

RFMXLTE_VAL_ACQUISITION_BANDWIDTH_OPTIMIZATION_ENABLED_FALSE

0 (0x0)

RFmx does not optimize acquisition bandwidth and will be based on the Nyquist criterion. The value of the acquisition center frequency is the same as the value of the RFMXLTE_ATTR_CENTER_FREQUENCY that you configure.

RFMXLTE_VAL_ACQUISITION_BANDWIDTH_OPTIMIZATION_ENABLED_TRUE

1 (0x1)

RFmx positions the acquisition center frequency to acquire the least bandwidth based on the configuration and span needed for the measurement. This helps in reducing the amount of data to process for the measurement, thus improving the speed. However this might cause the LO to be positioned at a non-dc subcarrier position, hence the measurement sensitive to it should have this attribute disabled.
