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• Email of test results• Email 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, EN55013..• EN50130-4, EN60601-1-2...• IEC/EN61000-4-3, IEC/EN61000-4-6

from low frequency - 40GHzusing 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

Supported Equipment• Agilent/HP

856x, 85xx, 444x (pres), 740x, 441x, 43x, 837xx, 83650, 85310, E825x, 8673

• Rohde & SchwarzFSEK, ESCS, ESAI, ESHS, ESMI ESVS, ESCI, ESU, FSP, ESI, SMx, NRVS

• Sunol, EMC Test Systems, HD• Field Probes

AR6001, AR5000, AR5080, WG, HI4455, HI6105, HI6005

• Amplifiers, IFI and AR• Switch drivers, HP

Drives can be changed by the users, signal source drivers are simple to develop

Report Output• Standard Vasona Print Out• HTML Output• Text File (to be used for import into

word)• GIF Graphical Output (to be used for

import into word and for HTML)

Future development• Further amplifier control• Above 1GHz SVSWR measurements• Additional traffic generator control• Additional receiver sweep

capabilities• Other equipment drivers
