Design and Function

The R&S SR8000 FM transmitter family is used for transmitting broadcast signals in band
II (VHF).

Depending on the configuration, individual transmitters are available in different power
classes from 100 W to 2500 W.

This chapter describes the transmitter's design and the functions of its components.
