8.2.4.4 Search Parameters
The iNetVu controller supports DVB-S and DVBS2ACM carriers. The recommended method of
satellite search is DVB using DVB-S/S2, followed by DVB reference satellite search with RF
search being the last option of choice. If using RF search, a
valid RF frequency
must be
entered and is highly recommended; this can be the service frequency or any other valid RF
frequency from a known carrier (preferably taken from Modem parameters). If no valid
frequency is known, then 10MHZ increments may be added to the lower range value until
satellite acquisition. The tuner range frequency must be in the range of 950 MHz
– 2150MHz.
Search Method
DVB or RF search are selectable from the drop down window. DVB will search directly on DVB-
S1 or DVB-S2 carrier and lock on it. DVB is the option of choice to use when searching for
satellite. RF option will allow the user to base satellite searching and peaking strictly on RF
instead of DVB. This method of searching could be used when the user is having a tough time
finding the transponder data for a specific satellite, or if no transponder data exists. The
controller will then peak on the modem signal when the satellite is found. RF search should be
used as a last resort after DVB and or DVB with reference satellite. The search will go into full
search mode automatically if the regular search fails to lock on satellite signal.
AZ Window Size
The Search Window is the area of the sky which the iNetVu
®
Mobile System will search for the
desired Satellite. It uses a rectangular window and searches for the Satellite using smaller
concentric windows until the desired Satellite is found. The default Azimuth (Horizontal) range is
60
on each side of the Target Point. Increasing the size of the Search Window will increase the
ability to find the desired Satellite, although increasing the Search Window will also increase the
search time.
RF Override/Threshold
Used by the iNetVu
®
Mobile Software to begin a signal optimization process for peaking on a
Satellite signal after initially locating it. This field should only be used if the RF threshold is to be
overridden. Ka Band systems with single TRIA cable will have the RF threshold set to 75 by
default (service dependent), this allows the RF Signal to be in operation range (RF Signal==70
on iNetVu Controls window) thus allowing the search process to begin. The RF Threshold can
also be manually set to any value ranging from 40 to 60 which will display the true value of RF
Signal on the iNetVu Controls window. Setting the RF Threshold to 30 will put the search into a
