Qam - Tuning Setup - BridgeTech VB20 User Manual

6.14.2 QAM - Tuning setup

In this view the operator can define frequencies that will be used by the QAM
demodulator for tuning. A name is associated with each frequency, and this name will
be used by the probe when referring to the stream. The frequencies and some
associated key parameters are shown in the QAM tuning list. Each entry in the list may
be edited by clicking the Edit field.
To add a new frequency to the list click the Add new tuning button. A pop-up window
will appear allowing the user to enter tuning parameters.
When one set of tuning parameters has been defined it is possible to click the button
Import from NIT in order to have the other frequencies automatically added to the
list, as defined in the Network Information Table analysed by the probe. Default values
will be assigned to parameters that are not a part of the NIT. Please refer to section
QAM - Threshold for a description of the Auto threshold functionality.
Clicking the Import from NIT button will open the NIT Import popup view.
