2.8.12 Frequency Domain Information
The following describe the indicators associated with FFT (Fast Fourier Transform) analysis. FFT data can be plot-
ted in the Data Collection window by setting the Time Domain / FFT / Histogram selector to FFT (Figure 14).
2.8.12.1
Displays the x-axis value of the cursor on the FFT display.
2.8.12.2
Displays the y-axis value of the cursor on the FFT display.
2.8.12.3
Indicator for the signal-to-peak noise ratio (decibels).
2.8.12.4
Indicator for the signal-plus-noise-plus-distortion to noise-plus-distortion ratio (decibels).
2.8.12.5
Indicator for the signal-to-distortion ratio, 4 harmonics are used in the calculations (decibels).
