The Graph Screen
Fig. 14 shows the Graph Screen. This screen displays the data in a graph format. A grid can be placed on the
graph by pressing the Grid on/off button. The graph screen also has zoom and scroll functions using the two white
handles at either end of the x-axis.
The Noise Analysis Screen
Once data has been read from the AD7718 ADC, it is possible to perform some analysis on it. Fig. 13 shows
the ADC Noise Analysis Screen. This screen displays the maximum and minimum codes read from the AD7718
ADC (in decimal and hexadecimal), as well as the average code, the average value and the RMS and Peak-Peak
noise values. From this screen it is possible to display the data on a graph or as a histogram of codes. Figures
14 & 15 show the Graph and Histogram screens.
