DVB-S/S2 parameters
6.2.4
As soon as the receiver has completed the synchronization process, several parameters are shown
on the display. When LOCK appears, it means that the digital receiver is receiving a valid data
stream. In contrast, UNLK means that either the quality of the signal that is present is insufficient,
or the parameters of the receiver do not agree, or no DVB-S/S2 signal can be received at this
frequency.
If the receiver has synchronized, the set standard (DVB-S/S2) and the current FEC (Forward Error
Correction) are displayed.
For DVB-S2, the modulation scheme (here 8PSK) and the presence of pilots are also displayed.

After the program search has been successfully completed (see Chapter 12 MPEG Decoder) the
provider and the satellite position is shown in the upper right corner. This information is extracted
from the NIT.
Special receiver settings
6.2.5
The device allows specific parameters in the DVB-S/S2 receiver to be changed.
If the measuring instrument is working with modified receiver settings, an inverted “
!
” symbol
appears on the display.
These settings are volatile. This means that after the device has been switched off and on or the
range has been changed, the measuring receiver switches back to the standard settings.
