The Keysight E5387A is a connectorless soft-touch probe designed for direct contact with target board signal pads, eliminating the need for physical connectors on the device under test. Using micro spring-pin technology, it accommodates board surface variations and contamination while maintaining reliable electrical contact. The probe integrates with Keysight logic analyzers via 90-pin cable connectors and includes a top-side retention module for secure attachment without requiring back-side access.
Technical Specifications
• Channels: 17 total (16 single-ended or differential data channels; 1 single-ended or differential clock channel)
• Equivalent Load Capacitance: Less than 0.7 pF
• Maximum Data Rate: Greater than 2.5 Gb/s (limited by connected logic analyzer)
• Minimum Signal Amplitude: 200 mV peak-to-peak (Vmax – Vmin)
• Differential Input Amplitude: V+ – V– ≥ 200 mV peak-to-peak
• Input Impedance: High impedance; capacitive loading is the primary frequency-dependent consideration
– Key Features
• Micro spring-pin technology for reliable pad contact across varied board conditions
• Top-side retention module eliminates need for board backside access
• Five retention modules (Agilent part number E5387-68701) supplied with probe
• Compatible with lead-free board finishes
• Requires pre-designed soft touch connectorless footprint on target board
• Low capacitive loading ( 2.5 Gb/s)
• Differential and single-ended signal measurement
• In-system probing where connector space is unavailable
