Frankly, I … [Read more...]
Multi-tone Testing Can Save Both Time and Money
Jason Smith, Manager Applications Engineering; Pat Malloy, Sr., Application Engineer; AR/RF Microwave Instrumentation, Souderton, Pennsylvania, USA Given the huge amount of time required to conduct a radiated immunity test, it is no wonder operators “dream” of ways to improve efficiency to speed up the test. The musings generally go as follows: Can one antenna cover the … [Read more...]
Calibration of Toroidal Current Measurement Probes at High Frequency
Alastair R. Ruddle, Ph.D., MIRA Ltd., Nuneaton, UK Toroidal current transducers are widely used in EMC measurements, both for monitoring currents flowing on single cables or cable bundles and for injecting currents onto such cables or cable bundles. The latter forms the basis of a well-established approach to susceptibility testing (bulk current injection) that is used in the … [Read more...]
