6. Configuration of the STR and the
DVB Tuner
The STR (Searching and Tracking Reference) and the DVB tuner can be configured
manually from the ACU front key or from the remote software (SCS Ver. 1.7.2).
Regardless of whether they use the ACU front panel or remote software to configure the
STR and the DVB tuner, users should at least prepare all the information required to
configure the STR and the DVB tuner, namely: satellite orbit location and polarity,
searching and tracking reference, compatibility of LNB LO frequency, etc.
6.1 Deciding on the Searching and
Tracking Reference
With the VS61 antenna, there are multiple search and tracking options, as previously
discussed. Operators need to decide which searching and tracking option to use from
among multiple selections.
The searching reference is used to provide a “sense”, on the basis of which the antenna
determines whether it is pointing to the correct satellite or not. Please refer to 4.2
Searching & Tracking Reference for a detailed explanation of its operation.
Lock-bit searching is preferred to threshold searching because the latter cannot
guarantee the correct pointing out of the desired satellite, although its searching speed will
be faster than that of lock-bit searching.
Recommended
Preference
Searching Reference
Very High DVB Carrier Lock with Reliable DVB carrier : As the DVB tuner
provides a very fast response, this reference will result in the fastest
searching speed while guaranteeing targeting accuracy.
High External Lock with external device: This option will find the
satellite a little slower than the DVB carrier lock because the current
searching speed is tuned to iDirect’s response time, which is not as
fast as that of the DVB tuner. However, this option, if available, will
guarantee that the antenna always targets the correct satellite as
long as an external device can provide the RX lock signal. One
