11. E2678B Differential Socketed Head with Damped Wire
Accessory
This E2678A/B probe configuration provides maximum connection reach and
flexibility with good signal fidelity but lower bandwidth for measuring differential
or single-ended signals.
Figure 43 E2678B with Damped Wire Accessory
The damped wires must be soldered to the circuit that you are measuring. This
configuration can probe circuit points that are farther apart than other
configurations. This probe head come with a damped wire accessory that includes
two 160 W resistors.

NOTE
The E2678B is a direct replacement for the E2678A that provides a more robust connection
between the E2678B head's socket and printed circuit board. The E2678B’s performance and
fit are identical to that of the E2678A.
