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.
23 wrz 2024 · As the bandwidth of the oscilloscope increases, the signal rise time that can be measured with it decreases. The rise time is associated with the 10-90% amplitude. ... Calculation Example What is the rise time associated with a 50 MHz bandwidth? The calculator is used to find T rise = 0.35 / 0.05 = 7 nanoseconds.
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.
21 lis 2006 · Choosing an Oscilloscope with the Right Bandwidth. Bandwidth is the specification that most engineers consider first when they select an oscilloscope. This article provides some guidance on how to select an oscilloscope with the appropriate bandwidth for digital and analog applications.
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.
Determine the minimum bandwidth of an oscilloscope (assume Gaussian frequency response) to measure signals that have rise times as fast as 500 ps (10-90%): f knee (10-90%)= (0.5/RT) = (0.5/0.5 ns) = 1 GHz 20% Accuracy: BW = 1.0 x f knee = 1.0 x 1 GHz = 1.0 GHz 3% Accuracy: BW = 1.9 x f knee = 1.9 x 1 GHz = 1.9 GHz
