Level-dependent acoustic signal

In the function, “level 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, ◄►. In the RP menu, the receiving frequency can be changed in this manner.

Selecting demodulation for DVB-C measurement

QAM64

Mode ￿

Symbol rate entry

6.900 SR1 ￿

With this button, the type of demodulation, QAM64, QAM128 or DOCSIS QAM64 (Softkey designation = DOC64 Mode) is selected. The setting is taken over for the constellation analysis.

For correct level measurement of digital signals, you can choose between 4 pre-set symbol rates (In DVB-C mode: 6,900; 6,111; 6,952 and 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!
