3.3.3.1 Analog Input Data Capture Features

This section describes the features available in the Analog IP (input) data capture display of the GUI. This page auto updates to reflect the channel-specific input configurations selected in the Channel Selection section.

The analog input page provides an interface to the conversion results of the analog input channels.

Analog data is captured, as shown in Figure 3-12, by clicking on the Capture Data button. The analog inputs page also provides user options for the following:

  • Number of samples per the enabled analog input channels

  • A drop-down option for increasing the oversampling rate

  • A drop-down option to change the SCLK frequency

  • A drop-down option for entering the desired sampling rate

  • A drop-down option for selecting input channel displayed when in manual mode. When in Autosequence, all channels selected would be displayed simultaneously

A table is also available with helpful attributes of the sampled data including, the minimum, maximum, and mean sample codes along with the peak-to-peak range of the sampled data and standard deviation. These values are populated after every data capture.

Within the Analog IP page, the captured samples can be displayed in three different formats:

  • Time Domain

  • Fast Fourier Transform (FFT)

  • Histogram
