What is EMC Testing and what type of Instrumentation Amplifiers are used?

What is EMC and why does it require testing?

Electromagnetic compatibility (EMC) is the part of electrical engineering that deals with the unintentional generation of electromagnetic energy. This type of energy can cause a range of undesired effects such as electromagnetic interference (EMI) and even physical damage to certain types of equipment.

The goal of EMC Testing is the examination of whether equipment (from every day items and appliances like dishwashers, washing machines and cars to safety-critical equipment like communications devices, radar systems and plane engines, are affected (and how) within an electromagnetic environment.

What type of Instrumentation Amplifiers are used for EMC Testing?

TMD has developed a range of high power pulsed TWTAs (Travelling Wave Tube Amplifiers) – up to 40 kW – specifically for EMC HIRF (High Intensity Radiated Fields) testing.

EMC Test laboratories using this range of Ultra High Power Instrumentation Amplifiers have generated 14,000 V/m, easily complying with the most demanding test requirements – RTCA/ DO-160G and L. They can achieve well over 10 kW. Other standards covered include: MIL Standard, EUROCAE and AIRBUS ABD 100.

Alongside our range of TWT Instrumentation Amplifiers TMD also now offers a full range of solid state amplifiers for EMC Testing. Designated the PTCS Series, these instrumentation amplifiers have been developed specifically for use at frequencies below 18 GHz.
