Transmitter-studio link
The
transmitter-studio link of a
radio or
television station sends
telemetry data from the remotely-located
transmitter back to the studio for monitoring purposes. The TSL may return back the same way as the
studio-transmitter link, or it can be embedded in the station's regular broadcast signal as a
subcarrier.
Data such as transmitter power, temperature, VSWR, voltage, modulation level, and other status information are returned so that engineering staff can correct any problems as soon as possible.
