SPeCTRUM ANALyzeR MODe

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

automatically identify harmonics and quickly analyze frequency content by

making measurements 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 fequency content.

Spectrum analyzer style controls simplify waveform analysis in the frequency domain.
