Four Useful Tips for Using Affordable Benchtop Spectrum Analyzers
In this column, we discuss several important features of a spectrum analyzer not covered in previous articles that are worth your consideration.
A Capacitively Coupled Pin Injection Method for Troubleshooting Immunity Issues
Although most modern RF amplifiers have a high voltage device rating against impedance mismatch, special care is needed to prevent impedance mismatch. To avoid impedance mismatch of the power amplifier, often an attenuator is also recommended to be connected between the output of the power amplifier and the flying probe.
Using an AM Radio as an Effective Troubleshooting Tool
An AM radio can be useful for finding both radiated emissions and ESD events. Understanding how radio works is essential for engineers to use this low-cost technology to troubleshoot complex EMI issues.
Cable Antennas and Ferrite Cores
In this column, the author offers a brief summary of a more systematic approach for using ferrite cores on cables. This summary can serve as a “ferrite core checklist” for design and test engineers.
