6.12.3  COFDM - COFDM threshold (VB250)

The probe will raise an alarm if one of the threshold settings associated with a COFDM 
frequency is violated. Note that this alarm may be disabled in the 

ETR 290 - ETR 

thresh. - Edit 

view (Input interface checks).

In the COFDM threshold template list the 'Refs' column shows how many streams are 
associated with each COFDM threshold template.
To add a new threshold template to the list click the 

Add new threshold

 or 

Duplicate selected

 button. A pop-up window will appear allowing the user to enter 

parameters. 
One or more threshold templates may be deleted or edited by highlighting them and 
clicking the 

Delete selected

 or 

Edit selected

 button.

The predefined threshold templates 

Default

 and 

Analog carrier

 cannot be edited or 

deleted.
