This Report describes the measurement procedures to determine the technical parameters of monitoring receivers and monitoring systems. This Report does not describe all possible solutions and also not automatically always the best solution for determining a parameter. The Report describes in one section the verification of the key parameters of a monitoring receiver and in another section the verification of the technical parameters of monitoring stations and other integrated systems like direction finders. Both sections can show an overlap in contents and even bear the same name. However these items should be treated as different parameters. The reason for splitting the specifications in key parameters and station parameters is the fact that monitoring receivers can be bought either as separate devices, or as an integrated system where the separate receiver parameters sometimes cannot be determined.
