ROUBLESHOOTING
This chapter discusses basic troubleshooting procedures for the Terrasat
Communications, Inc. line of products.
Maintenance
In general, Terrasat products are self-contained and require little maintenance.
However, for optimum performance Terrasat recommends that users inspect the
mechanics of the system every three to six months and perform the following:
• Clean the antenna feeds to keep them clear of obstructions.
• Check cables and connectors for signs of wear, damage, or loose connections.
• Check all fan intakes and exhausts to ensure that they are clear of debris.
Fault Isolation
Use the information in this section to assist in determining whether a Terrasat unit is
faulty. The intent is to determine a “Go” or No Go” situation based on alarms
indicated thought the M&C ports as well as by measuring certain signals using test
equipment.
Receive L-band Output Verification
If low or no Rx output power is detected, begin troubleshooting by checking the
output of the LNB. Look for interference by contacting the satellite controller or
checking with a spectrum analyzer. You can also contact the distant end to check their
transmit status.
If you are sure that there is no interference and that the link is still up from your distant
end, continue to
step 1 .
