Tektronix 4-SV-BAS Spectrum View

Spectrum View frequency domain analysis

Varenr: 4-SV-BAS

Spectrum View (optional)

It is often easier to debug an issue by viewing one or more signals in the frequency domain. Oscilloscopes have included math-based FFTs for decades in an attempt to address this need. However, FFTs are notoriously difficult to use for two primary reasons. First, when performing frequency-domain analysis, you think about controls like Center Frequency, Span, and Resolution Bandwidth (RBW), as you would typically find on a spectrum analyzer. But then you use an FFT, where you are stuck with traditional scope controls like sample rate, record length and time/div and have to perform all the mental translations to try to get the view you’re looking for in the frequency-domain. Second, FFTs are driven by the same acquisition system that’s delivering the analog time-domain view. When you optimize acquisition settings for the analog view, your frequency-domain view isn’t what you want. When you get the frequency-domain view you want, your analog view is not what you want. With math-based FFTs, it is virtually impossible to get optimized views in both domains.

Spectrum View changes all of this. Tektronix’ patented technology provides both a decimator for the time-domain and a digital downconverter for the frequency-domain behind each FlexChannel. The two different acquisition paths let you simultaneously observe both time- and frequency-domain views of the input signal with independent acquisition settings for each domain. Other manufacturers offer various ‘spectral analysis’ packages that claim ease-of-use, but they all exhibit the limitations described above. Only Spectrum View provides both exceptional ease-of-use and the ability to achieve optimal views in both domains simultaneously.
