3.1.1 Interface Configuration

Within the interface configuration section of the GUI, three different configurations are available: Vref (V), Capture Channel, and Samples. The Capture button begins ADC conversions based on the configuration options selected.

The Vref (V) drop down is by default set to 5 V to match the VA voltage provided on the EVM. Only change this option if an external VA is used. Enter the voltage used in the Vref (V) input to assure measurements made by the GUI reflect the external VA.

The Capture Channel drop down allows a single channel to be sampled from the eight ADC analog input channels. There is also an option to select all channels, which consecutively sequences all eight channels.

The Samples drop down selects the number of samples to be captured in the next set of measurements.
