Moku:Lab spectrum analyzer is considered as a 'real-time' spectrum analyzer. It down-converts the signal once according to the frequency window and then performs an FFT. This ensures the instrument has a higher spectral resolution while maintaining a reasonable measurement speed. Detailed explanation can be found in this application note.
