Receiver performance requirements
Radio surveillance spectrum - Signal analysis and identification

The performance required of a listening receiver is very similar to that of an interception receiver as described in [TE 6 891] . The same superheterodyne structure and channelization filters are often used. However, there are substantial differences in some performance requirements, which are detailed below.

• Synthesizer speed and spectral purity

  Speed is not of prime importance for a listening receiver. The spectral purity of the synthesizer is generally improved, as the response time of...
