2.2.1.6 Orion 5850 Modulator Types
The Orion 5850 can operate with different modulator types, the trade-offs being better
radio performance versus higher data throughput. The changes can be made via
software, using either the Orion NMS / GUI or an SNMP client application.
Modulator types and frequency bands that were tested and approved for compliance
with FCC regulations are specified in Sections 2.2.1.4 and 2.2.1.5.

NOTE 1: Changing the modulator type of an Orion 5850 RF Unit may take up to 30
seconds. During this period, the link will not be available. Changing the RFU
modulator type does not support Auto Recovery thus; the modulator type of the remote
station must be changed before the modulator type of the local station is changed.
2.2.2 RF Power Output Options
The RF Unit is designed for use in countries that have adopted FCC standards. It is
possible to adjust the output power on the RFU using the supplied NMS software or a
