3.3.3 Data Capture Tab

The data capture tab displays the conversion results of the sampled data of the enabled channels. As Figure 3-12 shows, clicking the red Capture Data button commences a sample data set. This page also displays the sampling mode configuration used to capture the data. There is also a checkmark option to repeatedly capture the sample size selected. This tab features two pages to display both the analog input and the digital inputs:

  • Analog Inputs: The sample and conversion results for each enabled analog input is displayed in this page. The results can be displayed in three methods: time domain, Fast Fourier transform (FFT), and histogram.

  • Digital Inputs: The enabled digital input channels are displayed in this page and can be polled for the current logic state.
