22 wrz 2020 · The crucial test for any 70Mhz (or any other) bandwidth Oscilloscope (and probes) is to accurately display 70Mhz square wave in this case. Applying Nyquist sampling, means the rising and trailing edges of that 70Mhz square wave will display as a 400 pico Second slope.

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”
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.
tolerances are a challenge for oscilloscopes so this steps through how to make accurate measurements. The last article is about how Rohde & Schwarz has expanded its high-performance R&S RTP oscilloscope family in terms of both bandwidth, and functions for debugging and analysis.
21 lis 2006 · Whether your scope has a Gaussian response, maximally-flat response, or somewhere in between, the lowest frequency at which the input signal is attenuated by 3dB is considered the scope's bandwidth. Oscilloscope bandwidth and frequency response can be tested with a swept frequency using a sine wave signal generator.
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.
