Spread Spectrum Clocking, Spread Spectrum Modulation (SSM) (Part 1)
In this video we show you the frequency behaviour of a spread spectrum modulated carrier signal by conducting a basic spread spectrum modulation (SSM) live experiment. Tutor: Nikolaus Juch Chapters: 0:00 Experimental Setup 0:48 Unmodulated Carrier Signal 1:05 Manually Changing the Carrier Frequency 1:40 Configuring SSM 2:23 Carrier Signal with SSM Equipment used: Rohde&Schwarz FSV Signal Analyzer + DC Block Settings: Center Frequency = 500 kHz Frequency Span = 200 kHz RBW = 1 kHz Ref. Level = 90 dBµV Rigol DG1022 Arbitary Waveform Generator Settings: Waveform = Sine Frequency = 500 kHz Amplitude = 100 mVrms FM – Settings: Deviation = 50 kHz Modulation Frequency = 20 kHz Modulation Shape = rectangular Institute of Electronics / Institut für Elektronik: https://ife.tugraz.at https://www.tugraz.at Social Media: / ife.tugraz.at / ife.tugraz.at / ife-tugraz iMooX: http://www.imoox.at
