The Main ADC Noise Analysis Screen
Once data has been read from the AD7719 Main ADC, it is possible to perform some analysis on it. Fig. 14 shows the
Main ADC Noise Analysis Screen. This screen displays the maximum and minimum codes read from the AD7719 Main
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 15 & 16 show
the Graph and Histogram screens. The Aux ADC Noise Analysis Screen performs the same function on data from the
Aux ADC.
The Main ADC Graph Screen
Fig. 15 shows the Main ADC 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.
