TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• The Future Of EMC Test Laboratory Capabilities

  The complexity of modern day electronics has resulted in the need for better EMI diagnostic capabilities at EMC test laboratories to combat the increase in EMI compliance failure rates. One solution is to use real-time mode which enables visualization of the spectrum to provide insight in the identification of the source of failing EMI emissions. This white paper describes the cause of the shift in failure rate that many companies are experiencing, the need for increased speed in testing, and the revolutionary EMI diagnostic capability built into modern EMI receivers.

• Five Hints For Successful Measurements In Noise

  Noise typically limits the overall performance of any wireless system and impacts a spectrum analyzer’s ability to measure very low amplitude signals while maintaining high accuracy and fast sweep speed. This app note presents five tips to improve the measurement sensitivity and accuracy for small signals.

• Field Probe Correction Factors

  To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.

• Evaluating Exposure To Pulsed Magnetic Fields With The ELT-400 Tester

  Narda's ELT-400 Tester is designed for measuring low frequency magnetic fields and evaluating the field exposure that occurs in workplaces and in public areas. This application note discusses the possibilities for ELT-400 analysis.

• Making Differential Measurements With Copper Mountain Technologies VNAs

  Many engineers prefer to perform differential measurements with 4-port instruments when characterizing electrical properties and S-parameters. This app note discusses balanced and differential circuits and demonstrates such measurements on a common-mode filter through the use of split-ring resonators.
