The only meaningful way to view this data is in the frequency domain, 
NOT the time domain. In other words, spectra and waterfall. Few 
lab-quality spectrum analyzers have anything close to sufficient 
resolution to see it, but spectra displays with Elecraft rigs, and full 
SDRs like Flex, ANAN, and even SDR receivers DO have this capability.
