Figure1. Relation between signal rise time and bandwidth(2) I used to limit the speed of signals, both analog and digital, to the minimum required bandwidth, and this can be done easily with filters. One of the simplest filters is the RC-filter, which is easy to implement and easy to ...
Despite the different bandwidths, a 12-GHz and a 20-GHz real-time oscilloscope will capture the same harmonic content of the PCIe Gen3 PRBS23 signal. Sign in to download full-size image Figure 5.2. Frequency spectrum of a PCIe Gen3 PRBS23 pattern. The rise time of the same signal is ...

That quantity is related to the rise and fall time. If those times are equal, they may be estimated to be 0.35 divided by the 3-dB bandwidth. Note that when modulation frequencies reach the bandwidth limits, one does not only experience a reduction of responsivity, but also phase changes....
The relation between the 20-80% rise or fall time and the 10-90% rise or fall time depends heavily on the exact shape of the rising and falling edges. Signals subject to large amounts of skin-effect loss, for example, exhibit an exaggerated ratio between the two measures of signal edge...
bandwidth here. A simple risetime test will not provide information on the shape of the scope's frequency response. In the absence of a suitable sinewave source, this method has been popular as an alternative and is still used for the oscilloscopes with a very high bandwidth, above 6 GHz....

To validate the model and the measured rise and fall times, it is necessary to validate the performance in terms of a communication system. Since the nanosecond laser diode used to obtain the rise time measurements cannot be modulated with an independent, random sequence of pulses, it was repla...
It is good to learn at this point that the larger the bandwidth the faster the system, i.e., the shorter the rise time, but this is usually at the cost of excessive overshoot. Such relations are further elaborated in Chapter 10 on Fundamental Limitations, various designs in Chapter 9, an...
