Quantifying Power Spectrum Results
Use the marker knob to read the amplitude at any measured frequency. Rotate the knob on the AGILENT 35670A front panel until the marker indicator (the small diamond following the spectral trace) is placed at the frequency of interest. The frequency and amplitude at this bin is presented as X and Y values at the top of the trace. Units of [Hz] and [Vrms] or [grms] identify the results.
Special marker features such as peak tracking can speed analysis. To always track the peak amplitude and frequency, follow these steps:
•Press the [Marker] hardkey.
•Press [PEAK TRK ON OFF] softkey (F6) until ON is highlighted.
The frequency and amplitude of the peak bin in every trace will be determined and displayed.
