Log Frequency Spectrum Display Program with the S-seriese oscilloscope
Display the Log frequency spectrum of DC power supply noise measured by s-series oscilloscope
To help users more easily understand the effectiveness of noise suppression components
Reason to evaluate the DC power supply noise using frequency domain measurement.
Checking the amount of voltage fluctuation of power supply in the time domain is important for evaluating the power delivery network.
In addition, the comparison of noise spectrum in the frequency domain is useful for understanding which frequency noise suppression components work effectively.
Reason to evaluate the DC power supply noise using Log frequency.
Noise suppression components (LC filter, bypass capacitor, DC-DC converter) make an effect depending on Log frequency. In the datasheet of noise suppression components, characteristics are described in Log frequency. To confirm whether these components are really effective in the power supply noise, checking DC power supply noise spectrum using Log FFT is the best way to evaluation.
Log Frequency Spectrum Display Program for S-series oscilloscope
The measurement results are shown on the display of the S-series oscilloscope quickly
No need to transfer the data and making graph using external PC.
Y-axis supports not only V but also dBm, dBuV, W unit
-various units used for noise evaluation are available
Y-axis can plot using Log with V and W unit
-small and large values can be shown on one screen using Log-Y plot
Two traces comparison is available
-useful for comparing characteristics of noise source and victims.
- useful for comparing characteristics of defective and non-defective products
