The setup for the ProBus interface is shown in the following figure. This interface also allows the selection of input
impedance, 50 /1 M.

Another universal probe interface advantage is the ability to switch between two probe setups. This function is
remotely programmable allowing the interface to operate like a switch.
The characteristics of the universal ProBus/ProLink Interface are shown in the following table. Each of the
interfaces provide power to the probe. An I

C interface allows communication with the probe which permits probe
recognition and interaction. This adds to the flexibility of the system as the scope can sense and control each
probe.

The WavePro 740Zi and 760 Zi oscilloscopes offer the universal ProBus/ProLink probe interface which allows
dual inputs in the DC to 3.5 GHz range and a dedicated high bandwidth interface in the range of 4 through 6 GHz.
The ability to select four out of eight inputs provides unheard of connection flexibility and eliminates the need for
costly, easy to lose adapters.
