| Description: | Specifies the measurement method for adjacent channel powers (ACP) measurements. When the NIBTSA_ACP_MEASUREMENT_METHOD attribute is set to NIBTSA_VAL_SPECTRAL_MEASUREMENT_METHOD_SWEEP, the toolkit finds the time-domain power within each resolution bandwidth (RBW) filter bandwidth that exists within the bandwidth used in each spectral acquisition. The toolkit traces the peak power of each of these RBW filter bandwidths. When the NIBTSA_ACP_MEASUREMENT_METHOD attribute is set to NIBTSA_VAL_SPECTRAL_MEASUREMENT_METHOD_FFT, the toolkit performs several FFT measurements on overlapping sets of acquired samples. After this, the toolkit computes the peak powers for each of the bins across all FFT outputs. The toolkit adjusts the results for a resolution of RBW bandwidth and traces this result. The results for the sweep and FFT methods may not be identical. The default value is NIBTSA_VAL_SPECTRAL_MEASUREMENT_METHOD_FFT.
