Meters & Testers

Shedding light on frequency and wavelength

July 20, 2022 By David Herres Leave a Comment

Today, an advanced multimeter such as the Fluke 287 in volts mode accurately displays frequency. High frequencies are displayed in a bench-type frequency counter, which can read above 100 GHz. At still higher frequencies, measurements are made indirectly via heterodyning to down-convert the signal. Using a diode or similar device as a mixer, a frequency […]

Key considerations for RF power measurement equipment

June 29, 2022 By Bob Buxton Leave a Comment

boonton RF measurements

The choice of power sensor and meter greatly depends on the qualities of the signal being measured. Bob Buxton, Boonton Electronics Today’s complex modulation schemes and pulsed communication modes have brought the need to measure RF power ever more accurately and efficiently. There are multiple technologies available for the measurement of RF power, falling into […]

Measuring and using static electricity

May 12, 2022 By David Herres Leave a Comment

static electricity

Many moons ago, a future member of our editorial staff was playing with his very first multimeter. He was a farm kid. One of his first experiments was to put the negative lead of the meter on a ground rod and the positive lead on one of the metal bands used to reinforce the interlocking […]

Radio altimeter flight-line test set adds fiber optic delay

April 27, 2022 By Lee Teschler Leave a Comment

viavi

The ALT-9000 universal radio altimeter (RADALT) flight line test set adds fiber optic delay to traditional radio frequency (RF) testing, enabling it to test all types of RADALTS on the market today. The RADALT measures an aircraft’s altitude above the terrain, by transmitting a radio frequency (RF) signal down to the ground and receiving a […]

What’s all this triplen harmonics stuff?

January 20, 2022 By David Herres Leave a Comment

Unless your background is in ac power, it’s possible you haven’t run into the term triplen harmonic. Triplen harmonics have to do with the third harmonic. Even-numbered harmonics do not normally exist in power systems due to symmetry between the positive and negative halves of the ac cycle. It is the odd-numbered harmonics that engineers […]

Current Digital Issue

A frequency you can count on There are few constants in life, but what few there are might include death, taxes, and a U.S. grid frequency that doesn’t vary by more than ±0.5 Hz. However, the certainty of the grid frequency is coming into question, thanks to the rising percentage of renewable energy sources that…
