Level-dependent acoustic signal

beep,“ a 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, ◄►. The
receiving frequency can be changed in this
manner in the RP menu.
Selecting demodulation for DVB-C measurement
With this button, the type of demodulation, QAM64, QAM128 r DOCSIS QAM64
(Softkey designation = DOC64 mode), can be selected. The setting is taken over
for the constellation analysis.
Entering symbol rate
For correct level measurement of digital signals, you can choose between 4 preset
symbol rates (In B-C mode: 6,900; 6,111; 6,952 d 6,875.). It is also possible to
change the preset symbol rates by numerical entry. In the DVB-C range, symbol
rates can be programmed from 0.5 –7.2 Ms. This programming is taken over for
the constellation analysis. With the [MHz] button, the entry is completed.
For correct level measurement of signals, the correct symbol rate must be set!
