Prior to the digital revolution in electronic instrumentation, oscilloscopes displayed waveforms on cathode ray tube screens. Modern digital oscilloscopes universally have flat screens. The flat screen is light, thin, consumes far less energy, and is less expensive to manufacture. All agree that it is a great improvement. The one advantage of CRT technology is that […]
The difference between histograms and spectrograms
Despite their similar names, histograms and spectrograms are totally different ways of displaying a signal or function in a digital storage oscilloscope (DSO). Both are useful in organizing and analyzing electrical waveforms, but the type of information that is displayed and the conclusions that may be drawn from them are worlds apart. Histograms and spectrograms […]
New power rail probes solve key measurement challenges
The TPR1000 and TPR4000 power rail probes combine with the 12-bit 5 or 6 Series MSO mixed signal oscilloscopes from Tektronix to offer what’s said to be the lowest system noise of any power-rail measurement solution available in the market today. The new probes are backed by a complete set of connectors for small, difficult-to-access […]
The difference between waveform settings and output settings in Tektronix MDO3000 series oscilloscope internal AFGs
Most digital storage oscilloscopes include an internal arbitrary function generator (AFG). In the Tektronix MDO3000 instrument, there is a port on the back panel labeled AFG Out. To control the AFG and display its output, connect a BNC cable to this port and plug the other end into one of the analog channel inputs or […]
Exploring the difference between a digital oscilloscope and a spectrum analyzer
Traditionally, only the spectrum analyzer was capable of displaying electrical and electromagnetic signals in the frequency domain and the oscilloscope took control of the time domain. More recently, each instrument has become competent in the other’s territory. But this overlapping tendency is far from absolute. Oscilloscopes, working in the Math>FFT mode, have always had a […]
Affordable data streaming and visualization service targets individual engineers
A cloud-based data streaming and visualization service for individuals includes unlimited data streaming and beautiful visualizations and is priced at $9.99 per month or $99 per year. The service is free for students. The technology is from Nashville, Tenn.-based Initial State Technologies Inc., acquired by Tektronix earlier this year. The cloud-based Initial State platform provides […]
T&M LEAP Award winners announced at gala dinner
At the LEAP Awards dinner gala in Costa Mesa, Calif., the following companies were awarded trophies in the category of Test & Measurement. This year’s inaugural LEAP Awards competition honored ground-breaking new products that set a new standard for innovation. Judges rated candidates on categories that included societal impact, industry impact, technical sophistication, creativity, and […]
RF menus in the Tektronix MDO3000 oscilloscope
Many oscilloscope users become adept at acquiring signals in the time domain and using Math>FFT in mixed domain oscilloscopes to display signals simultaneously in time and frequency domains. This is excellent for demonstrating the fundamental relationship between these different display modes, and the whole thing is user-friendly and intuitive. In a Tektronix MDO3000 oscilloscope, at […]
User review: the new Tektronix AFG31000 Series arbitrary function generators
In the consumer electronics boom following World War Two, a rapidly-growing number of homes contained analog CRT-based TVs, and repair shops soon appeared on every street. Technicians found these complex devices could best be serviced by injecting a synthesized signal at various points and accessing it downstream by means of an oscilloscope, thus isolating the […]
Oscilloscope technology – What lies ahead?
Oscilloscope technology advanced rapidly from its early 19th Century roots through the triggered sweep and digital/flat-screen transformation in the 1980s. The trend has accelerated. Bandwidth and sampling rates have expanded exponentially. Additionally, new features and measuring and display capabilities have emerged. In this context, one wonders what lies ahead. The major oscilloscope manufacturers maintain robust […]
