3.4 Using the Capture Tab

An example data capture display is shown in Figure 3-6. In this step, the necessary updates to the Capture settings are made to capture the time domain data and to get a good frequency domain result. First, update the number of samples to at least 32k to get good frequency domain results (for example, accurate FFT display, SNR data, and THD data). Next, select the Hanning type window to eliminate spectral leakage in the FFT result.

When these changes are made, press the Start Capture button to collect time domain and frequency domain data. Select the appropriate tab to view data for channel A or channel B.
