11 lip 2023 · Oscilloscope analog bandwidth can be higher than Nyquist frequency for repetitive signals. This is called equivalent-time sampling. The oscilloscope will interleave samples from multiple repetitions of the signal to achieve higher effective samplerate, while the analog system must be able to pass the frequency in question.

Scope BW Calculation Step #4: Calculate required bandwidth. Step #1: Determine fastest rise/fall times of device-under-test. Source: Dr. Howard W. Johnson, “High-speed Digital Design –A Handbook of Black Magic”
26 cze 2024 · To calculate oscilloscope bandwidth using the 3 dB rule, follow these steps: 1. Determine the Rise Time: Measure the rise time (tr) of the oscilloscope, which is the time it takes for the signal to transition from 10% to 90% of its peak value. 2. Use the Formula: Calculate the bandwidth (BW) using the formula: BW = 0.35 / tr. 3.
Introduction. Bandwidth is the specification that most engineers consider first when they select an oscilloscope. In this application note we will provide you some helpful hints on how to select an oscilloscope with the appropriate bandwidth for both your digital and analog applications.
provide you with some helpful hints on how to select an oscilloscope with the appropriate bandwidth for both your digital and analog applications. But first, let’s define oscilloscope bandwidth.
24 mar 2020 · Oscilloscopes with a maximally-flat frequency response have a sharper roll-off and a sampling rate of about 2.5 times the oscilloscope bandwidth should be sufficient. In this article, we’ll examine two important specifications of a digital oscilloscope: analog bandwidth and sampling rate.
