Method for testing an amplification path for telecommunications satellite repeater

A method for testing an amplification path of a satellite repeater, said path being connected to at least one first antenna for receiving usable signals and a second transmitting antenna for broadcasting said usable signals, wherein the amplification path makes it possible to frequency amplify usable signals from a plurality of communications channels, said channels being situated in a first frequency band, the amplification path being adapted to the first band, wherein the satellite comprises at least one signal generator of a subsystem that is configured to enable generation of telemetry data to a second transmission antenna for reception thereof on Earth, the method comprising:

• defining a test signal that includes the selection of a carrier frequency situated in the first frequency band;
• configuring the repeater to enable:
• transmission of the signal generated by the signal generator
• of the telemetry command management subsystem to the amplification path, the signal generator being connected to the amplification path to be tested;
• switching of the amplified test signal to the second transmitting antenna via the amplification path, the amplification path being connected to the second transmitting antenna;
• analysing the parameters of the signals that have been defined and amplified by the amplification path and emitted by the transmitting antenna after receipt of signals from the Earth.
