1130B-Series Probes User’s Guide

2. E2677B Differential Solder-in Head with Full BW Resistors

This probe configuration provides the

full bandwidth signals and the lowest

capacitive loading for measuring both

single-ended and differential signals.

This head allows a soldered connection into a system for a reliable, hands-free

connection. At the tip it uses a miniature axial lead resistor with 8 mil diameter

leads which allows connection to very small, fine pitch targets.

Figure 24

E2677B

The probe head resistors must be soldered to the circuit that you are measuring.

Because of the small size of the resistor leads, it is easy to solder them to very

small geometry circuits.
