Keysight / Agilent / HP E5383A Single-ended Flying Leads with 40-pin Cable Connector

The Keysight E5383A is a single-ended flying lead probe set engineered for logic analyzer signal acquisition on target systems with dispersed or non-standard probing points. The set delivers 17 channels—16 data channels plus 1 clock channel—enabling flexible access to signals across randomly located nodes. Connection options include 20 included IC test clips for direct attachment to component leads, five ground leads for reference establishment, or direct connection to designed-in connectors. The probe accommodates 0.63 mm square pins or 0.66–0.84 mm diameter round pins.

## Technical Specifications

• **Channel Count:** 17 channels (16 single-ended data + 1 single-ended clock)
• **Load Capacitance:** 1.5 pF equivalent
• **Minimum Signal Amplitude:** 600 mV peak-to-peak
• **Included Accessories:** 20 IC test clips, 5 ground leads
• **Weight:** Approximately 1 lb

## Key Features

• Single-ended measurement architecture for direct signal probing
• Low parasitic load at 1.5 pF simplifies high-frequency signal integrity analysis
• IC test clip attachment eliminates need for board modifications
• Ground lead set provides flexible reference point establishment
• Pin compatibility spans both square and round contact geometries

## Typical Applications

• Logic state and timing analysis on prototype and production boards
• Signal characterization where PCB test points are not available
• Multi-channel synchronous data capture across distributed measurement nodes
• Device bring-up and debug workflows requiring minimal target system modification

## Compatibility & Integration

The E5383A interfaces with logic analyzers equipped with 40-pin cable connectors. This probe is commonly deployed with Keysight’s 16500 series logic analyzer platforms, which support modular measurement capabilities including state/timing analysis, pattern generation, and digitizing oscilloscope functions.
