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, ◄►. The receiving frequency can be changed in this manner in the RP menu.

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!
