Bandwidth Rise Time Calculator

This calculator converts between the rise time of a signal and the bandwidth of the system carrying it, in either direction. Enter a rise time in nanoseconds to get the required bandwidth, or enter a bandwidth in gigahertz to get the rise time it implies. The two are linked by a constant, so knowing one always fixes the other. Engineers use it when picking an oscilloscope or a cable fast enough to show an edge without rounding it off.
