Spectrum View - A New Approach to Frequency Domain Analysis on Oscilloscopes

Spectrum View is a new way of performing spectrum analysis on an oscilloscope. The ADC in the oscilloscope sends high-speed digitized data down two paths. One path leads to hardware decimators which determine the rate at which time domain samples are stored. The second path leads to digital down-converters also implemented in hardware. This approach enables independent control of the time domain and frequency domain acquisitions, allowing optimization of both waveform and spectrum views of a given signal. It also makes much more efficient use of the long but finite record length available in these instruments.

In this webinar, we will be exploring the following:

  • Any analog signal may be presented as a waveform, spectrum, or both
  • Time domain waveforms and spectrum are synchronized
  • Waveform and spectrum display may be independently adjusted
  • Settings are made with spectrum analyzer controls such as Center Frequency, Span, and Resolution Bandwidth (RBW)
  • Multi channel spectrum analysis
  • The difference between Spectrum View and how it differs from the traditional oscilloscope FFT functions
