9. E2677B Differential Solder-In Head with Medium BW
Resistors
The E2677B with medium BW resistors (150W mini-axial lead) probe configuration
provides medium bandwidth measurements of differential or single-ended signals.

The longer resistor length allows connection to widely spaced points or points in
tight areas. 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. This configuration can probe circuit points that are
farther apart than the full bandwidth configurations.
