Shows that they use the scope with assume 100 MHz bandwidth. Because of this the clock signal looks sinusoidal. 

They have to use a scope with at least 500 MHz bandwidth to look at 100 MHz clock frequency.


And they should use an active probe.

In addition the setup enough good for measurement of a high frequency device.

They should use a solder-down on board with proper bypass capacitors.
