Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

If you’ve been tuned in to Electonic Design’s articles this past year in the test & measurement arena, you’re probably aware of a series by Colin Mattson (Keysight Technologies) on advanced ...

Nanoscopy describes the ability to see beyond the generally accepted optical limit of 200–300 nm. Stimulated emission depletion (STED) microscopy, developed by Stefan W. Hell and Jan Wichmann in 1994, ...

Remember: before you start using rules of thumb, be sure to read the Rule of Thumb #0: How to use them wisely. What is Bandwidth? Bandwidth is the highest sine wave frequency component that is ...
