The Keysight E5385A is a single-ended logic analyzer probe that delivers high-fidelity digital signal acquisition across 34 channels via a low-loading surface-mount Samtec connector. Engineered for dense circuit boards, this probe excels at debugging and verifying complex digital designs with minimal circuit intrusion. The probe supports data rates to 1.5 Gb/s and accommodates signal amplitudes as low as 500 mV peak-to-peak, making it suitable for modern high-speed digital applications.
