Tryout: Uni-T UPO1202 200 MHz oscilloscope
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 Generator ($182), we at EE World bought one and, … [Read More...] about Tryout: Uni-T UPO1202 200 MHz oscilloscope
How to calculate and apply the inverse discrete Fourier transform: part 3
The inverse transform can create a time-domain waveform where no waveform has been before. In part 2 of this series, we used the discrete Fourier transform to convert a waveform from the time domain to the frequency domain, operated on the frequency-domain data, and used the inverse transform to … [Read More...] about How to calculate and apply the inverse discrete Fourier transform: part 3
What are the three levels of TEMPEST testing?
Telecommunications electronics materials protected from emanating spurious transmissions (TEMPEST) testing, also called emission security (EMSEC) by the National Security Agency (NSA), is an NSA specification and is defined in the NATO SDIP-27 standard. TEMPEST is designed to deny unauthorized … [Read More...] about What are the three levels of TEMPEST testing?
Review: Tekbox TBCG4 harmonic comb generator
The Tekbox TBCG4 harmonic comb generator produces a wide range of known frequencies for EMC immunity testing and routine checking of EMC chambers. I've used harmonic comb generators for decades in various applications, including antenna measurements, cable resonance measurements, and … [Read More...] about Review: Tekbox TBCG4 harmonic comb generator
Free and low-cost online EE tools aid in design
Downloadable and online free and low-cost EE tools help engineers design and analyze circuits. The internet is full of EE tools from equipment manufacturers, semiconductor manufacturers, independent EEs and hobbyists. Some are web-based that you can use with just a browser. Some you need to … [Read More...] about Free and low-cost online EE tools aid in design
How to calculate and apply an inverse FFT: part 2
In part 1 of this series, we looked at the formula for the inverse discrete Fourier transform and manually calculated the inverse transform for a four-point dataset. Then, we used Excel’s implementation of the inverse fast Fourier transform (IFFT) to verify our work. Could we try something more … [Read More...] about How to calculate and apply an inverse FFT: part 2
How to calculate and apply an inverse FFT: part 1
The inverse Fourier transform (inverse FFT or iFFT) reverses the operation of the Fourier transform and derives a time-domain representation from a frequency-domain dataset. In early 2024, EE World published a series on the Fourier transform, which can convert a time-domain signal to the … [Read More...] about How to calculate and apply an inverse FFT: part 1
How can EMI be weaponized?
Electromagnetic interference (EMI) can be an unwanted and disruptive aspect of electronic system designs. It can also be amplified and weaponized. EMI is being weaponized in purpose-built high-power microwave (HPM) tactical systems that devastate electronics without the side effects of physical … [Read More...] about How can EMI be weaponized?
Controlling EMI and improving sustainability
Optimized designs require less electromagnetic interference (EMI) shielding and other materials, improving sustainability. Improved EMI performance extends system life and reduces e-waste, further enhancing sustainability. More sustainable shielding materials are being developed for use when … [Read More...] about Controlling EMI and improving sustainability
Engineers use AI/ML to improve test
Engineers can use AI/ML to reduce test development time, analyze test data from manufacturing, automate visual inspection and calibration, and identify counterfeit components. Here's how some do it. Testing takes too much time; just ask any engineering or production manager. Shortening … [Read More...] about Engineers use AI/ML to improve test

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 […]
