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
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 […]
Hand-held spectrum analyzers come in 1.3 and 2.7-GHz versions
The Aim-TTi PSA Series 3 RF Spectrum Analyzers are available in 1.3 GHz and 2.7 GHz versions and have long battery lives with improvements over the previous Series 2 instruments, even rivalling more expensive handheld RF products. Improvements include a lower noise floor for increased sensitivity, a new frequency counter, additional RMS, Sample, and Average […]

Ohm meter features low stimulus voltage for sensitive components
The AltoNovus OR-01 OhmRanger-LCV Low Compliance Voltage Ohmmeter is an accurate, affordable, portable meter which can measure a wide range of resistances simply and quickly. Individually factory-calibrated, this meter measures resistances from greater than 100 MΩ down to 10 Ω. Additional built-in features include a signal-to-noise measurement, which indicates how much noise, variation, and ac […]
High-performance LCR meter spans 4 Hz to 10 MHz range
The R&S LCX family of LCR meters serves all established impedance measurements plus specialized measurements for selected component types and provides both, the high accuracy required in R&D, and the high speed needed in production test and quality assurance. With its supported frequency range from 4 Hz to 10 MHz, the R&S LCX is suitable […]
What’s all this triplen harmonics stuff?
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 […]
