I ran a test to measure the bandwidth of the Electronics Explorer's oscilloscope using a fast pulse generator that produces square wave pulses with a rise time of ~2 ns.
The attached image shows the rise time measured by the Electronics Explorer. Note that the oscilloscope was set to oversample and average, as the image also shows.
Surprisingly, the oscilloscope yielded a rise time of ~4 ns. Using the formula 0.35/(rise time), the calculated bandwidth of the Electronics Explorer's oscilloscope is ~88 MHz. Although oversampling and averaging was required to get this result, this is a surprisingly excellent bandwidth.
Does this result seem reasonable or am I doing something wrong?
