3. E2678B Differential Socketed Head

This probe configuration allows a 

removable, hands-free connection that 

provides full bandwidth with a minor 

increase in capacitance over the probe 

head for probing differential and single-ended signals. Additionally, 3.6 cm resistor 

tip wire accessories are provided for high fidelity lower bandwidth probing of 

signals with very wide spacing. It is recommended that a 25 mil diameter plated 

through hole on the board for mounting the lead resistors.

Figure 25

E2678B

The 82

Ω

 axial lead resistors are soldered to the circuit that you are measuring. The 

socketed differential probe head is plugged onto the resistors. This makes it easier 

to move the probe from one location to another. Because of the larger size of the 

resistor leads, the target for soldering must be larger than the solder-in probe 

heads.

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.
