Question 1

Automotive 600V/m Radar Pulse Test Solution

Accepted Answer

Many hazardous electrical events in the environment can have adverse effects on a vehicle’s systems, causing potentially unsafe situations. These events can be generated by “off-vehicle” and “on-vehicle” sources and can either be natural or man-made.

To protect against these events, automobile manufacturers have developed Electromagnetic Compatibility (EMC) standards to test electronic components and whole vehicles. Read entire article here.

Question 2

EMC Immunity Multi Tone Testing Theory and Practice

Accepted Answer

Multi-tone testing has many benefits. While the multi-tone method was initially implemented to increase the speed of IEC 61000-4-3 radiated immunity testing, it has been found that this method also improves equipment efficiency, offers greater flexibility to truly test the equipment (EUT) under real-world threat conditions, and can be fully compliant with standards.

Other benefits include more efficient use of finite financial and human resources and faster time-to-market for new and enhanced products. Read entire article here.

Question 3

Importance of Mismatch Tolerance for Amplifiers Used in Susceptibility Testing

Accepted Answer

RF amplifiers have a nominal output impedance of 50 Ω and ideally would only be used in applications where the load impedance is also 50 Ω.

This ideal situation results in maximum power transfer from the amplifier to the load, where all power is absorbed in the load with no power reflected back to the amplifier. Read entire article here.

Question 8

Shielding Effectiveness and Shielded Enclosure Leakage Detector System

Accepted Answer

Today both commercial and military industries are more reliant than ever on electronics. In addition, the need to protect those electronics from potential threats has become even more vital.

Threats like electromagnetic interference (EMI) and High-Altitude Electromagnetic Pulse (HEMP) can interrupt or even destroy the functionality of unprotected electronics. Get the detailed information here.

Question 9

Telecommunications Testing Using Amplifier Research

Accepted Answer

On September 2nd, 1837, Samuel Morse demonstrated a device for transmitting information by electromagnetic energy through conductive wires. 60 years later, Guglielmo Marconi founded the Wireless Telegraph & Signal Company, and since then, the world has never looked back.

Progressive advancements have climbed the electromagnetic spectrum and pushed device technology to ever greater heights. This has been especially true since 1980 when cellular communications systems became commercially viable. Get the detailed information here.
