Agilent/Keysight E5378A

The Agilent/Keysight E5378A is a 34-channel logic analyzer probe for high-density target systems, delivering single-ended signal acquisition with minimal loading effects. The probe integrates 32 data channels plus 2 configurable clock channels (single-ended or differential) and connects via a 100-pin Samtec surface mount connector to compatible logic analysis modules. Data capture rates reach 1.5 Gb/s with sensitivity to signals as low as 250 mV peak-to-peak, making it suitable for low-voltage signal environments.

The probe's equivalent load capacitance of 1.5 pF minimizes impact on target circuitry.
