7.1 Viewing the Computational and Threshold Parameters
You can display the computational and threshold parameters by navigating to the Parameters
View tab on the Utilities View. See the preceding tables for a description of each of the displayed
values.
7.2 Computational and Threshold Parameters File
The threshold parameters and the computational parameters are stored in an XML-formatted file named
“computationalParameters.xml. It is highly recommended that you not modify any of the factory-config-
ured configuration values. If you must modify the XML file, it is recommended to download the file from
the TXpert and use it as a template.
7.3 Downloading the Parameters from the TXpert
You may download the parameters from the Utilities View. The following steps describe the process.
