You need not spend a ton of money to get a feature-packed oscilloscope, provided you don't need high bandwidth. While the oscilloscope works well, the free software needs help. After seeing the Uni-Trend (Uni-T) UTG962E Function/Arbitrary Waveform … [Read More...] about Tryout: Uni-T UPO1202 200 MHz oscilloscope

How to use convolution to implement filters: part 4
A windowed sinc function can implement a low-pass filter, and a two-dimensional convolutional filter can blur or sharpen images. In part 3 of this series, we introduced a low-pass filter based on the Sinc function and described the need for windowing to compensate for sampling and … [Read More...] about How to use convolution to implement filters: part 4
Why engineers need IC ESD and TLP data
Design Engineers need ESD and TLP characterization data to make informed decisions to design robust circuits and systems. Engineers often review semiconductor data among several manufacturers when designing a circuit or system. While two or more ICs may perform satisfactorily under normal … [Read More...] about Why engineers need IC ESD and TLP data
How to use convolution to implement filters: part 3
A windowed sinc filter outperforms a moving-average filter in the frequency domain. In part 2 of this series, we described a type of convolution filter called the moving-average filter, and we demonstrated that it is effective at removing Gaussian white noise in the time domain but performs … [Read More...] about How to use convolution to implement filters: part 3
How to use convolution to implement filters: part 2
A moving-average filter can address white noise in the time domain but performs poorly in the frequency domain. In part 1 of this series, we defined convolution, denoted by the * symbol, and looked at a simple geometrical example of how it operates to produce a new function y(t) from two given … [Read More...] about How to use convolution to implement filters: part 2
How to use convolution to implement filters: part 1
Convolution is used in a variety of signal-processing applications, including time-domain-waveform filtering. In a recent series on the inverse fast Fourier transform (FFT), we concluded with a mention of convolution and its application to filtering. Convolution Q: What is convolution? A: … [Read More...] about How to use convolution to implement filters: part 1
What is second generation beamforming?
Second-generation beamforming refers to advanced designs using more sophisticated signal processing algorithms, larger antenna arrays, and the ability to generate higher quality, more focused beams that dynamically adapt to user movement and changing environments. This article looks at how basic … [Read More...] about What is second generation beamforming?
How are NRZ and PAM different in an eye diagram?
Eye diagrams are important tools in telecommunications for analyzing the performance of digital signals, such as noise, distortion, and intersymbol interference. This FAQ compares the non-return-to-zero (NRZ) and pulse modulation (PAM) formats, which are common ways of reading an eye diagram. NRZ … [Read More...] about How are NRZ and PAM different in an eye diagram?
Electrostatic Discharge (ESD): impacts and solutions
Electrostatic discharge (ESD) disrupts the normal operation of electronic components and systems. It can cause leakages, shorts, gate oxide ruptures, junction and metallization burnouts, and deterioration of resistor-metal interfaces. To protect semiconductor devices from ESD, engineers integrate … [Read More...] about Electrostatic Discharge (ESD): impacts and solutions
EMI from LED light fixture often exceeds regulatory limits
Conducted emissions from LED light fixtures at frequencies from 1 MHz to 30 MHz can interfere with amateur radio and several broadcast bands. Radiated emissions reach into the lower cellular bands. After recently moving to northern Colorado and setting up my EMC lab and amateur radio station in … [Read More...] about EMI from LED light fixture often exceeds regulatory limits
What is bit jitter, and what are its component jitters?
Bit jitter can be a problem. A digital data stream is composed of a series of rapidly changing “ones” and “zeros.” Bit jitter can make it difficult to tell the difference and result in data errors. This article begins by defining jitter, then looks at its component jitters, compares bit jitter … [Read More...] about What is bit jitter, and what are its component jitters?

What is the importance of resolution in an oscilloscope?
When looking at the oscilloscope feature of a multi-instrument device or when comparing two benchtop oscilloscopes, the first specifications that we look at are the bandwidth and sample rate. While these are incredibly important specs, often most design work is done well within the limits of most products and the more critical specification to consider is resolution. Did you know that while most […]
