Modulated RF power amps for pre-compliance immunity testing

June 8, 2018 By Lee Teschler Leave a Comment

TBMDA2

The TekBox TBMDA2/TBMDA3 Modulated Wideband Power Amplifiers are designed to create an inexpensive signal source for pre-compliance immunity testing of electronic PCBs and products. Driven by the tracking generator output of a spectrum analyzer, they provide the increased RF power outputs required by many test environments. With an input power range of up to -8 […]

Miniature data recorder rated for IP68

August 8, 2017 By Lee Teschler Leave a Comment

DTS SLICE IP68

The new SLICE IP68 data acquisition system is designed to capture physical signals in challenging environments. Targeted at applications with size or mass constraints, SLICE IP68’s 60×60-mm footprint makes it easy to embed in most test articles. The rugged housing is impervious to shock, water, and dust, making SLICE a candidate for testing in inclement […]

Characterizing sinusoidal signals with equations

May 12, 2017 By David Herres Leave a Comment

sinusoidal

Mathematics is the language we use to understand and communicate our knowledge about electrical relationships. It is easy to get overwhelmed by some of the complexity involved. The best approach is to begin at the most fundamental level and take it from there. Consider the realm of sinusoidal signals. First, a definition: A sinusoidal signal […]

Tiny recorders let crash test dummies take one for the Gipper

April 19, 2017 By Lee Teschler Leave a Comment

DTS crash test football helmet dummies

The University of Alabama at Birmingham’s (UAB) Department of Mechanical Engineering is developing new testing methodologies using crash test dummies to improve helmet testing and ultimately reduce concussions and traumatic brain injuries (TBI). In that regard, they are putting sensors and recorders inside crash test dummy heads to get biofidelic impact data. Miniature DTSSLICE NANO […]

In search of accuracy: Instrument calibration using frequency standards

March 1, 2017 By David Herres Leave a Comment

cesium clock

Accuracy as it relates to the measurement of electrical signals would seem to be a simple, straight-forward concept. In the simple case, a reading as shown in a digital display could be compared to that of a perfectly accurate instrument. The discrepancy, if any, could be expressed as a fraction of a percent. The difficulty […]

In search of accurate measurements — The speed of light

February 22, 2017 By David Herres Leave a Comment

interferometer

If an instrument is to give accurate measurements, it must first have been calibrated to a standard. In metrology, a standard (or etalon) is an object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity. Standards are the fundamental reference for a system of weights and measures, […]

Basics of working with I2C buses

January 13, 2017 By David Herres Leave a Comment

I2C buses

Back in olden days, parallel buses were used to link electronic building blocks. Today serial buses have largely replaced them. There are numerous components for many applications that have standard serial interfaces, and this trend makes serial technology a good choice for design engineers. Because there are fewer signal lines, serial bus electronics take up […]

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…
