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.
