Hughes DW4020 manual The receive modem is locked onto the desired satellite signal

2.At the Installation Menu prompt, enter a to obtain antenna pointing values and assigned satellite parameters. The

Antenna Pointing - Receiver screen in Figure 82 appears.

Figure 82: Antenna Pointing - Receiver

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 Gateway 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.

3.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.

4.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 DW4020 unit.
