Feature Descriptions MDM6000 Satellite Modem
The pure carrier is used during line-up and to perform cross polarization tests with the
satellite operator.
The test modulation settings are used for calibration and/or verification of the spectrum polarity.
In this case, a carrier is modulated by a rotating vector with a period of baudrate/n. This results in a
single spectral line at:
+clock/n offset from the pure carrier.
The following figure shows the constellation diagram and the result on a frequency analyzer of a
Test modulation clock/8.
