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
7/8 CR ➧
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
27.500
SR ➧
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)
MPEG
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“).
