| Description: | Specifies the minimum duration of the waveform to be acquired by the NI-RFSA. This value is expressed in seconds. If you set the NIWLANA_AUTO_DETECTION_STANDARD_MODE attribute to NIWLANA_VAL_ADS_MODE_OFF, the NIWLANA_ACQUISITION_LENGTH attribute specifies a common measurement length for all measurements that are enabled. However, if you enable more than one measurement, NI recommends that you set the following attributes instead, if the corresponding measurement is enabled. NIWLANA_TXPOWER_MEASUREMENT_LENGTH NIWLANA_CCDF_MEASUREMENT_LENGTH NIWLANA_GATED_SPECTRUM_MEASUREMENT_LENGTH NIWLANA_DSSS_POWER_RAMP_MEASUREMENT_LENGTH NIWLANA_OFDM_DEMOD_MEASUREMENT_LENGTH NIWLANA_DSSS_DEMOD_MEASUREMENT_LENGTH You cannot set the NIWLANA_ACQUISITION_LENGTH attribute along with any of the previous attributes. This attribute is ignored in the following cases: NIWLANA_OFDM_DEMOD_ENABLED and NIWLANA_OFDM_DEMOD_AUTO_COMPUTE_MEASUREMENT_LENGTH_ENABLED attributes are set to NIWLANA_VAL_TRUE, and no other measurement is enabled. The NIWLANA_DSSS_DEMOD_ENABLED and NIWLANA_DSSS_DEMOD_AUTO_COMPUTE_MEASUREMENT_LENGTH_ENABLED attributes are set to NIWLANA_VAL_TRUE, and no other measurement is enabled. If you set the NIWLANA_AUTO_DETECTION_STANDARD_MODE attribute to NIWLANA_VAL_ADS_MODE_PACKET_FILTER, the NIWLANA_ACQUISITION_LENGTH attribute specifies the waveform length to be acquired by the NI-RFSA. This attribute does not specify the measurement lengths for the measurements that are enabled. You must set the individual measurement lengths. The default value is 10 ms if you set the NIWLANA_AUTO_DETECTION_STANDARD_MODE attribute to NIWLANA_VAL_ADS_MODE_PACKET_FILTER, and 1 ms if you set the NIWLANA_AUTO_DETECTION_STANDARD_MODE attribute to NIWLANA_VAL_ADS_MODE_OFF.
