Thinking about RF/microwave signals

Options for generating and analyzing RF/microwave signals have expanded over the first half of this year, with companies introducing a variety of signal analyzers...

Speeding instrument setup, control, and communication

Experts and novices alike can use a helping hand when making measurements. Many test-and-measurement companies offer software tools with their instruments, helping to speed...

Smart factories leverage cloud, edge computing

Manufacturing is witnessing a transformation through the implementation of the smart-factory concept and factory-automation technologies, according to Markets and Markets, which has just published...

20-year PXI development has seen continued growth

PXI has blazed a trail since its introduction in 1997 by National Instruments with growth that has remained in the double digits, according to...

Engineers push to make the world greener and extend battery life

The drive for efficiency and long battery life implies that power considerations play a key role in designs—from battery-powered mobile devices and electric vehicles...

Triggering morphs to match application needs

When Tektronix introduced Howard Vollum’s Model 511 triggered-sweep oscilloscope in 1946, it was a game-changer. Triggering allowed users to isolate critical parts of a...

Modal math may not add up

Single-shaker vibration test systems have been used for many years to explore a test item’s resonances. Swept sine testing applies only one frequency at...

Transforming EMI measurements

Digital EMI receivers and real-time spectrum analyzers have become possible because of advanced ADC technology as well as the availability of high-speed DSP devices....

High or low density matters

Thanks to advances in relay and semiconductor capabilities, switching systems continue to evolve. Higher performance relays are available with the same or smaller size...

Extending the midrange definition

Today’s mid-range oscilloscopes include noteworthy innovations while predictably continuing the higher-wider-longer evolution. Gradual feature-set expansion in a general-purpose test instrument is to be expected....
