Agilent/Keysight E5380B

The Keysight E5380B is a 34-channel Mictor probe designed for high-fidelity signal capture in digital system debugging and validation. It connects directly to a device under test via an integrated Mictor connector, providing minimal signal distortion for accurate logic analysis. The probe interfaces with Keysight logic analyzers through a 90-pin cable connector, enabling straightforward integration into target systems requiring multi-channel digital signal monitoring.

Technical Specifications

• Signal Channels: 34 total channels - 32 single-ended data channels and 2 single-ended clock channels


• Maximum Data Rate: 600 Mb/s


• Equivalent Load Capacitance: 3.0 pF


• Minimum Measurable Signal Amplitude: 300 mV peak-to-peak


• Connector Footprint: 38-pin Mictor on target device


• Cable Interface: 90-pin connector to logic analyzer

Key Features

• Low loading impedance (3.0 pF) minimizes signal distortion and preserves signal integrity on the target board


• Supports data rates up to 600 Mb/s, suitable for contemporary digital system validation


• Optional support shroud prevents accidental probe dislodging in vibration-prone environments; compatible with PCBs up to 0.12 inches thick


• Compatible Mictor connector part numbers: Keysight 1252-7431 or AMP 2-767004-2


• Ground pin placement between signal lines enhances signal-to-signal isolation

Typical Applications

• Embedded system debugging and real-time signal capture


• FPGA and ASIC validation during design verification


• Multi-channel digital signal monitoring in target PCB integration


• Post-production validation and field diagnostics

Compatibility & Integration The E5380B interfaces with Keysight logic analyzers featuring 90-pin cable connectors, including the 16900 Series, 16800 Series, 16700 Series, 1660 Series, 1650 Series, and E9340 series instruments. The probe is compatible with the E5346A high-density probe adapter. Integration requires routing signals of interest to the Mictor connector location on the DUT; optimal signal integrity is achieved by connecting multiple ground pins to the target board's ground system.
