3.2.
Front page
The relevant information required for the function of the system are shown on the front page. The decisive thing
is the quality of the input signals and the utilization of the modulators.
3.2.1.
Bit error rate
The
bit error rate
of all four SAT IF tuners is shown on the left side. The amount of bit errors for the last
1,000,000 transferred bits is calculated.
3.2.2.
Fill level
The
fill level
of all four modulators is shown on the right side. 100% modulator fill level correspond to the
maximal net data rate of the output channel.
If the current fill level exceeds the maximal fill level, it may cause image disturbances, e.g. mosaic images.
The data rates of the programmes are not constant. They are dynamically changed by the sender. To ensure an
undisturbed reception, a reserve must absolutely be observed.
We recommend you to set the maximal fill level to 90%.
The number of choosen programmes (see 3.4 on page 19) and the configuration of the modulators (see 3.5 on
page 22) have an influence to the fill level.
3.2.3.
CI menus
If CA moduls are used in RFQ-845CI or RFO-845CI, the CI menu buttons on the front page are active (see 4.2
on page 31).
