MAIN WINDOW Menu Bar File
This allows the user to access the ID register, status register, offset register, and full-scale register.
This allows the user to read previously stored data for display or analysis, write the current set of data to a file for later use, and exit the program.
About This provides information on the revision of software used.
This selects the Quick Analysis window. The Quick Analysis window gives the user access to the following subset of control bits: Channel, Update Rate, Gain, and Reference. For access to all control bits, click Registers or Other Registers.
This allows the user to access the temperature demonstration software.
This allows the user to reset the AD7793 and set the registers to the power-up conditions as specified by the software (channel = AIN1(−)/AIN1(−), bias voltage generator enabled on AIN1(−), gain = 64, update rate = 16.7 Hz, internal reference).
This allows the user to exit the software. It serves the same purpose as Quit in the File pull-down menu.
Samples/Analysis This serves the same purpose as the Sample button. Waveform The gathered conversions are displayed in graph form. Histogram The gathered samples are used to generate a histogram Codes
This allows the user to read a number of samples from the AD7793. Noise analysis is then performed on the samples. These samples can be stored for further analysis. The sample size is entered in the Num Samples text box.
The gathered samples can be displayed in codes or in voltage format. When the Codes option is selected, the values are displayed as code. The Codes button changes to Volts. To display the information in volts, click Volts.
This allows the user to read a number of samples continuously. The software gathers a number of samples as specified by the Num Samples text box, performs noise analysis on the samples, and gathers the next group of samples.
By default, the internal reference is used. To use an external reference, set Reference in the Registers window to External. The value of the external reference should be entered in the External Reference text box.
This allows the user to access the configuration register, mode register, and IO register.
