LG U+ adopts Anritsu MT1000A for 5G rollout
Korean operator LG U Plus (LG U+) will use Anritsu’s Network Master Pro MT1000A supporting speeds up to 100 Gbps for 5G service. LG U+ is promoting the expansion of mobile backhaul and fronthaul networks for 5G services using the MT1000A. LG U+ was one Korean mobile network operator to offer LTE, as well as […]
High-def scopes handle three-phase power analysis
A three-phase power analysis software package brings single-phase and three-phase static and dynamic power analysis to the HDO8000A, HDO6000A and WavePro HD 12-bit High Definition oscilloscopes from Teledyne LeCroy. With the 3-Phase Power Analysis software package, research and development engineers can now use Teledyne LeCroy’s 12-bit-resolution oscilloscopes to better understand complex power conversion system and […]
Mitigating ac motor-shaft voltage and bearing currents
Bearing problems are the greatest single contributing factor in motor failure. Often motor damage happens before bearing wear is noticeable. To avoid expensive repairs and costly downtime, early detection is essential. Proper installation of replacement bearings and correct lubrication are critical. It is well known that insufficient lubrication brings early bearing failure, but many maintenance […]
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 […]
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 […]
Analog and digital modulation and modulation measurements
In amplitude modulation (AM), the amplitude of a carrier wave whose frequency remains constant changes in response to the modulating signal. In frequency modulation (FM), it is the frequency of the carrier that varies with the amplitude of the modulating signal. The carrier frequency deviates more when the modulating signal amplitude is higher. There are […]
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 […]
The difference between MDO and MSO displays with time domain and Fast Fourier Transforms
Mixed-domain oscilloscopes and mixed-signal oscilloscopes differ significantly in how they display waveforms. Both are useful because they permit users to simultaneously view different electrical aspects of equipment under investigation. The MDO displays a single signal simultaneously in the time and frequency domains, demonstrating how they change together. The MSO displays two different signals in the […]
