Voltage Sag Testing for Industrial Equipment—and a New Power Quality Measurement Technology
Andreas Eberhard Vice President Power Standards Lab Immunity from voltage sags is vital for reliable operation of our ever-more-sophisticated electronic controls and equipment. Every electrical product should be able to ride through typical voltage sags, but in many cases the first sag test occurs after equipment is installed and in operation. Select the appropriate sag … [Read more...]
Field Probes Offer High Performance in Compact Size
Teseq Inc., a developer and provider of instrumentation and systems for EMC emission and immunity testing, now offers two new USB / RS232 electric field probes. The PMM EP-600 and EP-601 active broadband field probes benefit from a true spherical symmetrical dipole configuration.

Using a Comb Generator with a Pair of Current Probes to Measure Cable Resonance
(A Useful Technique When a Tracking Generator is not Available) A comb generator RF source can be a handy substitute when a tracking generator is not available on a spectrum analyzer, EMC consultant Doug Smith says in this month’s Technical Tidbit. In this case, a USB powered comb generator RF source is used to supply the signal used to measure the resonant frequencies of a … [Read more...]
AR’s New “A” Series Amplifiers Are Smaller, More Powerful, And More Economical
Souderton, PA — October 21, 2009 — New innovations at AR RF/Microwave Instrumentation are enabling the company to produce smaller, more compact amplifiers with just as much power as the older, larger models. The new “A” Series amplifiers, for example, are 25% -- 50% smaller than previous models, yet the new size does not mean a reduction in power. These newer, smaller models … [Read more...]
New Antenna Mounting Adaptors
AR RF/Microwave Instrumentation has introduced three new antenna mounting adaptors that are uniquely designed to allow horizontal and vertical polarization changes during testing without removing the antenna from the tripod. The three new adaptors are designed to be compatible with existing AR antenna models. Adaptor Model AM1000 is designed for use with AT1000 and AT1000A … [Read more...]
