What follows is a description of the various windows that appear while the software is being used. Fig. 4. shows the
main screen that appears once the program has started. The printer port that will be used by the software is determined
automatically. There are three possible printer ports that can be handled by the software, LPT1 (standard), LPT2 and
PRN. The user can change to another printer port by clicking on the "Printer Port" dropdown menu. A brief description
of each of the buttons on the main screen follows:

Allows the user to program or read the on-chip registers of the AD7719.
Allows the user to read a number of samples from the AD7719 Main ADC.
These samples can be stored for further analysis or just displayed for reference.

samples can be stored for further analysis or just displayed for reference.
Allows the user to perform noise analysis on the data that has been read in from the
Main ADC.
Allows the user to perform noise analysis on the data that has been read in from the
Aux ADC.
Allows the user to perform a software or hardware reset on the AD7719.
Allows the user to read in previously stored data for display or analysis - user needs
to specify Aux or Main ADC data.
Allows the user to write the current set of data to a file for later use - user needs to
specify Aux or Main ADC data.
Provides information about the version of software being used.
Allows the user to display samples from the Main and Aux ADCs
simultaneously. These samples can be stored for further analysis or just displayed
