3. At the Installation Menu prompt, enter
a
to obtain antenna
pointing values and assigned satellite parameters. The
Antenna Pointing - Receiver screen in Figure 124 appears.
The SQF represents the strength of the received signal
relative to noise. SQF is an integer value between 0 and 99.
The SQF value is interpreted as follows:
–
0-29. The receive modem is not locked onto the desired
signal. The value increases as the DW6000 receives
stronger signal power.
– 31-99. The receive modem is locked onto the desired
satellite signal.
– 30. The receive modem is locked onto a satellite signal, but
is waiting for a message confirming that it is locked to the
correct signal. An unchangeable value of 30 indicates that
the receive modem is locked onto a wrong signal.
4. If the SQF is less than 30, refine the antenna pointing to bring
the SQF over 40 and to as close to 99 as possible. The SQF
message updates automatically. There is a delay of up to 10
seconds between the displayed and the current SQF value.
5. If you cannot achieve a satisfactory SQF, take the steps below
in the order suggested until the situation is corrected.
a. Check for unobstructed view to the satellite.
b. Refine antenna aiming.
c. Check LNB polarization.
d. Check receive symbol rate.
e. Replace LNB.
f. Replace entire DW6000 unit.
