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.
demodulating radar RF pulses with an oscilloscope. It reviews how to measure radar RF pulses with respect to frequency, modulation type (linear up/down, exponential, phase) chirp rate, modulation sequence, pulse repetition interval (PRI) and amplitude to judge if they fulfill your requirements.
Bandwidth is the frequency range of the oscilloscope, usually measured in Megahertz (MHz). It is the frequency at which the amplitude of the displayed sine wave is attenuated to 70.7% of the original signal amplitude. When measuring high-frequency or fast rise-time signals, oscilloscope bandwidth is especially critical.
typical 4 GHz Oscilloscopes are dimensioned for the flattest frequency response possible within the specified bandwidth, which means that the –3 dB point will lie outside of the specified bandwidth. This ensures that it is still possible to analyze and measure signals near to the upper bandwidth limit. As seen in Fig.1-4, measurements
