AutoProbe is an intelligent communication and power link between compatible
probes and Infiniium scopes. AutoProbe completely configures the scope for the
attached probe. For instance, it identifies the probe type and sets up the proper input
impedance, attenuation ratio, probe power and offset range, as needed.
