Spectrum Analyzer

Product number: PKI 4230

The world economies that are competing for business must provide high level security arrangements for the protection of corporate secrets, marketing strategies, financial information and business strategies. Thus they are facing new challenges every day. Eavesdropping detection is an important aspect in all fields of our world economy. PKI 4230 offers the tools for the detection of high frequency signals that are difficult to detect under toughest conditions.

PKI 4230 is a portable fast spectrum analyzer with the necessary functionalities to detect unknown, illegal, disturbing and abnormal radio transmissions across a wide frequency range. With these features PKI 4230 is the perfect tool for radio links, mobile phone stations, HF emission analysis, mobile phone provider, for the evaluation of communication channels, the investigation of misuse in crowded HF spectra and – most of all – for Eavesdropping Detection.
