- Click Wizard
- Choose Video Quality Analyzer in the pop up window.
- Set how long you want to monitor the video quality, also how often to sample the video traffic, and the saved result file name. By default, the test will monitor video traffic for 5 minutes, every 10 seconds STC will get a sample of the video traffic, the end test result will be saved as vqanalyzertest-YYYY-MM-DD.db file.
- Check the ports you are going to use to monitor video traffic, please pay attention to Layer2 Encapsulation parameter. If the video traffic you are going to monitor has vlan header or pppoe header, you need configure this parameter correctly, or the video traffic will not be able to detect by STC.
