How To Eliminate Common Power Meter Mistakes
 

Most measurement errors are the result of a poor setup, from using the incorrect detector type for the signal of interest to failing to make allowances for gating and various forms of modulation.

Filter Basics Part 7: Different Approaches To Q Factor
 

In part 7 of this series from Knowles Precision Devices, a deep dive is performed on the different ways to think about Q factor for the components going into your filter or for your filter as a whole. 

Indoor Connected Home Remote Camera Performance Analysis With XFdtd
 

This example discusses the performance, as simulated by XFdtd EM Simulation Software, of a generic remote camera that provides video surveillance around the house for security monitoring.

Multi-Tone Testing, Theory, And Practice
 

Multi-tone testing was initially implemented to increase the speed of immunity testing, but it also improves equipment efficiency, offers higher flexibility, and is fully compliant to standards. Multi-tones are used in measuring modern audio levels in audio devices, broadband devices, and in internet audio.

How To Power SiC Or IGBT Half Bridges In EVs
 

By considering some gate drive and flyback converter fundamentals, many of today's electric vehicle (EV) and hybrid electric vehicle (HEV) low-voltage challenges can be understood and solved.

Biconical Antenna Selection
 

For many years, most regulatory standards called for the use of a half-wave dipole antenna set for frequencies above 20 MHz. However, to reduce test time, broadband antennas such as the biconical antennas began to be accepted.
