About Satxpander Calculator
– The Calculator is an advisor tool that suppose to help users to clearly view different options of system configuration. The Calculator should support the process of choosing the most efficient and desirable configuration settings.
Using the Calculator
– The input of the calculator is one of the following:
● current working modulation DVB-S/S2
● CNR
● SNR
– For each one of the above possible comparison one should state the following requires parameters:
● link-margin
● Roll off
● Pilots On/Off
● Frame Size Normal/Short
● Bandwidth
