The performance of Equalink depends on many factors (the type of TWTA and its drive level, the
characteristics of the IMUX and OMUX filters, the uplink and downlink noise, the characteristics of
your signal, ...).
The Automated Equalink procedure is designed to automatically take into account all these factors
to configure Equalink in the best possible way with minimal user interaction.
A detailed document describing the automated Equalink procedure can be delivered
upon request.

In order to do a complete Equalink calibration, the following procedures are typically performed in the
presented order:
• Satellite Link Analysis (to verify the present conditions, such as the TWTA drive level, and uplink
and downlink noise level);
• Automated Linear Equalink Calibration (run and enable afterwards);
• Automated Non-Linear Equalink Calibration (run and enable afterwards);
• Satellite Link Analysis (to verify the link optimality and to give an overview of the gain of
Equalink).
For broadcast or distribution links that are using a single carrier per transponder, both linear and
Non-Linear pre-distortion can give much efficiency gain.
