Most electronics engineers and technicians have a good understanding of total harmonic distortion (THD). But there are a few elusive details that come into play during THD measurements. THD is the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. Properly speaking, the fundamental frequency is […]
Free firmware brings mixed-domain analysis to MSOs
Tektronix today released new firmware for the 5 Series and 6 Series MSO mixed signal oscilloscopes that unlocks a new analysis tool called Spectrum View. A free upgrade, Spectrum View allows you to perform mixed domain analysis on the big, high-resolution displays of the 5 and 6 Series MSOs. This mixed domain capability can be […]
User review: Connecting the Tektronix AFG 31000 AWG to the MDO3000 oscilloscope
The new Tektronix AFG 31000 Arbitrary Function Generator is noteworthy in that the Home screen, accessed by pressing the Home button on the front panel, permits the user to choose a Basic or Advanced mode. The Basic mode resembles a traditional AFG, with a library of internal waveforms and menus that permit the user to […]
Big waveform memory lets AWG handle EW testing, wireless comm apps
The AWG70000B Series Arbitrary Waveform Generator supports the testing of complex electronic warfare and wireless communications systems that require the ability to dynamically alter signal sequences during test scenarios. Those running complex test scenarios need to accurately recreate real-world signals and cycle through fast-changing signal tests quickly. To meet these requirements, Tektronix is bringing new […]
Cathode ray tube vs. flat screen displays in oscilloscopes
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 […]
