Normalized Site Attenuation (NSA)
A Guide to EMC Test Site Validation
This guide explains what Normalized Site Attenuation is, why EMC test site validation is important, how NSA measurements are performed, what equipment is required, and how antennas such as tuned dipoles, biconical antennas, and log-periodic antennas can be used in site-validation applications.
Shielding Effectiveness Test Guide
Just as interference testing requires RF enclosures, isolation systems in turn need their own testing. This document reviews some of the issues and considerations in testing RF enclosures.
Coaxial Cable Insertion Loss and VSWR Testing for EMC Applications
Regularly validating your test leads for insertion loss (S21) and Voltage Standing Wave Ratio (VSWR / S11) ensures measurement repeatability and precision while preventing costly re-testing. This comprehensive technical guide details the standard procedure for verifying high-performance coaxial cable assemblies using a Vector Network Analyzer (VNA).
Radiated Emissions Measurement Test Guide
This is a brief overview on how to perform a standard Radiated Emissions Measurement test. It includes how to set up, take measurements and calculate results.
The Engineer's Guide to Maximizing Dynamic Range in RF Testing
In RF testing, dynamic range is the critical measure of a system’s ability to detect weak signals without being masked by noise or distorted by high-power signals. Maximizing this range is crucial for accurate measurement and requires balancing sensitivity, linearity, and strategic use of attenuation and filtering techniques to achieve precise results.
A Basic Bulk Current Injection Test Method
Here is an example of bulk current injection (BCI) test. Bulk current injection testing is to confirm that RF signals, when coupled onto interconnecting cables and/or power supply lines, will not cause degradation of performance or deviation from specifications of the equipment under test.
Power Amplifier and Test Systems Check
This test procedure describes how the small signal performance data of an amplifier is gathered and checked against previously recorded data. This is a fault finding step that establishes the health of the preamplifier.
