Vasona … The EMC Application An Overview

Overview History Overview and functionality Future Developments

History Vasona has been developed during the last 20+ years of EMC testing and development. After using other commercially available packages it was obvious that they do not provide the necessary functionality to effectively test to the wide range of EMC standards.

Functionality, Basic Tests Radiated Emissions Radiated Immunity RF Conducted Immunity RF Conducted Emission Other measurement techniques required to operate effective EMC laboratories

Examples of other functions Measurement processes, manual to complete automation NSA (typically 30MHz-1GHz) Insertion loss measurements (using signal generators, reference sources or tracking generators) Functionality to allow simple confidence check measurements Amplifier linearity checks Audio measurements, SPL and Voltage (CISPR 24) Preselector control Tower/Turntable speed control Transducer factor, simple data reduction

Non-std Advanced Features Network storage of factors files, equipment drivers and templates Storage of confidence check results on the network for simple recall and trend analysis Auto update of all network factors of test results of run time problems Radio measurements Traffic generator monitor (bit errors etc) Simple cable replacement

Typical Test Standards 47CFR15 GR1089 CISPR22, CISPR11, CISPR13… EN55022, EN55011, EN EN , EN IEC/EN , IEC/EN from low frequency - 40GHz using chambers, OATS, FAR, FSOATS … and other suitable facilities.

PC System Requirements Windows application, separate tests can be run/opened in each window. Win2K, WinXP or WinVista, National Instruments Card (IEEE488), Serial Port, Parallel, USB This is a large application which does need a higher power PC. It can operate on very slow PCs but it does distract from test operation
