Operating basics

Start the application

When you open the application after installation, the application checks for a file called Resources.xml located in the My TekExpress folder. If this file is not found, instrument discovery is performed before launching M-PHY Rx. The Resources.xml file contains information regarding instruments that are available on your network. If the application license was not installed using the TekScope menu Utilities > Option Installation selection, the application will allow 10 free launches. Each time you open the application without supplying a valid license key, one of the free trials is used.

To run the M-PHY Rx application, do any of the following:

■

From the TekScope Analyze menu, select Analyze > TekExpress M-PHY Rx.

■

Double-click any saved session file.

Exit the application

Activate the license

Use the following method to exit the application:

NOTE. Using other methods to exit the application results in abnormal termination of the application.

Click

2. Do one of the following:

■

on the application title bar.

If you have an unsaved session or test setup open, you are asked to save it before exiting. To save it, click Yes. Otherwise click No. The application closes.

A message box appears asking if you really want to exit TekExpress. To exit, click Yes.
