Digital Measurements
SAT DIGITAL menu
Calls up the previous
menu.
Level-dependent acoustic signal
In the function, “level
beep,“ an acoustic signal is
generated, whose pitch is
proportional to the received
signal level. With this
signal, it is possible to optimally align the
receiving antenna to a transmitter.
In this menu, the receiving frequency can be
changed using the cursor buttons, ◄►.
Convulsion code for Sat measurement
With this button, the convulsion code is set for demodulating the QPSK signals
from 1/2 to 8/9. The setting is adopted for the constellation analysis.
Symbol rate entry
You can choose between four preset symbol rates for correct level measurement of
digital signals ( in SAT mode: 22,000; 27.500; 20,000 and 27,500). It also possible
to change the preset symbol rates by numerical entry. In the SAT area, symbol
rates can be programmed from 0.5 ...32 Ms. This programming is adopted at the
constellation analysis. With the [MHz] button, the entry is completed.
The correct symbol rate must be set for proper level measurement of signals!
MPEG decoder menu (OPTION)
In this function, the PAL list (programme association table) and the respective PIDs
(packet identifier) of the transport stream are displayed. The desired programmes
can be selected in this menu and represented on the screen (refer to „MPEG de-
coder“).
