Ethernet tester includes 5 GHz WLAN support
The NetXpert XG2 Ethernet tester offers many of the same benefits and capabilities as the flagship NetXpert XG with the addition of several new hardware features, including 5GHz wireless local-area network (WLAN) support. Like the NetXpert XG, the NetXpert XG2 performs Bit Error Rate Tests (BERT) from 100 megabytes (MB) to 10 Gb regardless of […]
Tester handles all-in-one LMR, PMR and LTE radio testing
The CX300 ComXpert is a comprehensive communications test and alignment solution in an easy-to-use, ruggedized form factor. The CX300 is the first LTE-ready radio test set equipped to test both radio and broadband network infrastructure, helping today’s radio technicians ensure complete communications coverage. As the global public safety radio market rapidly transitions from analog to […]
Don’t touch that! Things they don’t teach you in circuits lab
The domain of most electronics engineers these days is confined to voltage levels ranging from microvolts on up to a few hundred volts. But when electronic equipment fails or there’s a problem with facility wiring, these same engineers may, in a pinch, be called upon to do basic troubleshooting of power levels far beyond their […]
Grounding considerations for renewable power generation
It pays to know the difficulties that can arise when testing and evaluating ground systems for solar panel arrays and wind farms. Jeff Jowett, Megger Industrial wind turbines are typically 280 ft high and getting taller. Their height makes them prime targets for lightning strokes that peak in less than 10 µsec while producing tens […]
Looking for ghostly goings-on with a milligauss meter
Tune in to TV shows that are purportedly about ghost hunting and you’ll often see people wandering around in the dark with an instrument called a milligauss meter. A milligauss meter detects changing magnetic fields. (It won’t detect static fields as from a bar magnet.) When a milligauss meter shows a reading during a ghosting […]
Benchtop optical power meters handle optical light measurements
The Newport 1938-R and 2938-R Benchtop Optical Power Meters are the next generation of the popular 1936-R and 2936-R instruments. Combining the advanced functions of their predecessors with an up-to-date CPU, touch screen, Android OS, and high-bandwidth electronic design, the single-channel 1938-R and dual-channel 2938-R are ideal instruments for advanced high speed, modulated light measurements. […]
Review: Using the Fluke 438-II motor analyzer
Fluke has come out with another superb electrical measuring instrument. It is the Fluke 438-II Motor Analyzer. Owners of the previous Fluke 435-II Power Quality Analyzer can download an upgrade that will add Motor Analyzer functions to their existing equipment. Full documentation including specifications and owner’s manuals for both of these members of the oscilloscope […]
The difference between an electrometer and a Geiger counter
In 1895 William Roentgen observed X-rays although he could not explain their mechanism. The following year Henri Becquerel demonstrated that certain compounds of uranium emitted radiation that resembled X-rays. He showed this activity differed from the phenomenon of phosphorescence. The radiation seemed to be emitted continuously from the uranium. Did this violate the well-known principle […]
Non-contact voltage true-rms ac/dc clamp meters measure voltage, current simultaneously
The new Fluke 377 FC and 378 FC Non-Contact Voltage True-RMS ac/dc Clamp Meters are the only clamp meters that make accurate non-contact voltage measurements without test leads. The Fluke 377 FC and 378 FC True-rms clamp meters use Field-Sense technology to make testing faster and safer, all without touching a live conductor. You get […]
