Spectrum Analysis Back to Basics – Definitions and Measurements

  • Modern designs demand more bandwidth for capturing high data rate signals and analyzing the quality of digitally modulated bandwidthsAerospace and Defense Radar– Chirp errors & modulation quality Satellite– Capture 36/72 MHz BW’s w/high data ratesMilitary communications– Capture high data rate digital comms & measure EVM Emerging communications W-LAN, 802.16 (wireless last mile), mesh networks- Measure EVM on broadband, high data rate signalsCellular Communications W-CDMA ACPR & Multi-carrier Pre-Distortion- High dynamic range over 60 MHz BW to see low level 3rd order distortion for 4 carrier pre-distortion algorithms Who needs wide analysis BW?59
