EEVblog 1718 - Cheap 1GHz Oscilloscopes are Useless? ($5 DIY 1GHz Resistive Probe)

What use is a 1GHz oscilloscope if it doesn't have a high frequency active probe interface? Well, there are several options including a cheap $5 DIY resistive probe. Practical demonstration of active FET probing vs Passive Probing vs DIY Resistive probing.
