SPECTRUM ANALYZER OPTION
Simplify Analysis of FFT Power Spectrum
Get better insight to the frequency content of any signal with use of the
Spectrum Analyzer mode on the HDO4000. This mode provides a spectrum
analyzer style user interface with controls for start/stop frequency or center
frequency and span. The resolution bandwidth is automatically set for best
analysis or can be manually selected. Vertical Scale can be selected as dBm,
dBV, dBmV, dBuV, Vrms or Arms for proper viewing and analysis while the
unique peak search automatically labels spectral components and presents
frequency and level in an interactive table. Utilize up to 20 markers to automati-
cally identify harmonics and quickly analyze frequency content by making mea-
surements between reference and delta markers. To monitor how the spectrum
changes over time, view the spectrogram which can display a 2D or 3D history
of the frequency content.
Spectrum analyzer style controls simplify waveform analysis in the frequency domain.
