Agilent/Keysight E5383B

The Keysight E5383B is a single-ended flying lead probe that connects directly to logic analyzers for real-time signal acquisition across dispersed measurement points. This 17-channel probe assembly provides 16 data channels and 1 clock channel, enabling access to signals at designed-in connectors, component leads, and board features via an included IC test clip. The probe’s minimal 1.5 pF equivalent load capacitance preserves signal integrity while supporting minimum signal amplitudes of 600 mV peak-to-peak (p-p).

– Technical Specifications

• Channels: 17 total (16 single-ended data + 1 single-ended clock)
• Equivalent Load Capacitance: 1.5 pF
• Minimum Signal Amplitude: 600 mV p-p
• Maximum Data Rate: Equivalent to attached logic analyzer’s data rate
• Pin Compatibility: 0.63 mm square pins or 0.66–0.84 mm diameter round pins

– Key Features

• Flying lead configuration enables flexible probing of randomly distributed test points
• IC test clip included for non-intrusive attachment to component leads and traces
• Direct connector interface for pre-designed measurement nodes
• Low input capacitance minimizes loading effects on target circuitry

– Typical Applications

• Post-silicon validation and debug on PCB assemblies
• Signal monitoring at scattered measurement points where probe cards are impractical
• Functional verification in designs with distributed signal paths
• Component-level acquisition where trace accessibility is limited

– Compatibility & Integration

The E5383B interfaces with Keysight logic analyzers equipped with 40-pin cable connectors, providing seamless integration into existing measurement setups. The probe accepts both square and round pin geometries, adapting to varied connector and component footprint designs.
