The Keysight (Agilent) E2678A InfiniiMax single-ended/differential socketed probe head delivers high-bandwidth access to devices under test through a plug-on socket connection. Part of the InfiniiMax probing system, this probe head enables both single-ended and differential voltage measurements with minimal loading, making it well-suited for integrated circuit and circuit board characterization. The E2678A integrates with Keysight InfiniiMax probe amplifiers and Infiniium oscilloscopes equipped with AutoProbe interface support.

– Compatibility & Integration
The E2678A works with Keysight InfiniiMax probe amplifiers, including the InfiniiMax II 1169A model. Integration with Infiniium and InfiniiVision Series oscilloscopes is facilitated through the AutoProbe interface, which enables automatic probe configuration and measurement setup. Note: The E2678A is obsolete; the E2678B is its current replacement.
