If the radio assembly is Ka-band and the text next to this checkbox reads Perform
ACP, you probably selected the wrong LNB. In this case go back to the Receive LNB
Selection screen and select the correct LNB.
Figure 28: DAPT Antenna Pointing Status window
Note: The DAPT Antenna Pointing Status window displays the DAPT test values as
each pointing test is completed. If you click
Close
before antenna pointing is
done, the values will be lost. Then you would have to click
Display Signal
Strength
again on the Receive Antenna Pointing screen to reopen the DAPT
Antenna Pointing Status window and begin pointing again.
2. Take the DAPT, squinter, and jumper cable to the antenna location.
Refer to the pointing guide for other equipment you may need.
3. Point the antenna as explained in Ka-Band Antenna Pointing Guide for
Bent-Pipe Satellite Networks (1038764-0001).
Important: Squinter pointing is a multi-step process. Read and follow the
pointing guide carefully. Make pointing adjustments to the antenna as instructed
in the antenna installation guide.
To complete squinter pointing, you must obtain a Pass value for:
•
Center validation
•
Azimuth validation
•
Elevation validation
For each validation test you can see the Es/No values and Pass/Fail result on the
DAPT Antenna Pointing Status window.
4. Perform the pointing validation steps described in the Ka-Band Antenna
Pointing Guide for Bent-Pipe Satellite Networks (1038764-0001).
Pointing is validated when all four validation fields show
Pass
, as shown in
Figure 30 .
