4.2.14 Tuner Configuration
The CMR-6000 can be configured to have a backup (secondary) configuration. The backup tuner
configuration allows the user to configure a backup configuration in the event the main carrier is taken
down. The CMR-6000 will only attempt to use the backup configuration in the event the primary carrier
is not available, and if a switch time of greater than 0 (zero) is set. If the unit is unable to lock to the
backup tuner settings, the unit will continue to switch between backup and primary frequencies based on
the switch time until lock is achieved.
4.2.14.1 Primary and Backup Tuner Configurations
Note the primary and backup can be completely different configurations, e.g.: the primary may be a
DVB-S2 service, but the backup may be a DVB-S service, or vice versa. Any valid configurations
supported by the CMR-6000 can be setup as primary and backup configurations.
LNB Frequency
The frequency of the Local Oscillator (LO) that resides in the Low Noise Block (LNB) amplifier located
at the antenna. For Ku-Band operation, the LO is typically 10,750 MHz for Ku-Band operation North
America and other common frequencies are 9,750 MHz and 10,600 MHz. For C-Band operation, 5,150
MHz is a common LO frequency. Please consult your LNB manufacturer for the LO in the LNB.
