7.5.2 Monitoring Modulator Status.
Quality of transmission could be verified on the basis of UHP modulator statistics and configuration (see Figure 46).
Figure 46 UHP Modulator statistics and configuration.
Parameters to be assessed to decide on the modulator status:
 Modulator interface is UP – a signal is sent to modulator output;
 Rate/bps and Packets – non-zero values of these indicators show traffic flow to the modulator
output.
If the remote Station does not receive the carrier of the local Station the following should be
performed:
1. Verify the physical connections between RF equipment, cable routes and the router;
2. Ensure correct pointing of the antenna to the satellite;
3. Monitor the level of the transmitted signal – SetLvl parameter. The transmitted signal power
must be sufficient to ensure successful operation of selected MODCOD. If necessary, increase
the transmission signal level (see Table 1 or paragraph 2.3.3);
4. It is not recommended to set the level of the transmitted signal higher than the compression
point in the RF transmitter (BUC).
