Agilent/Keysight E1682A

The Agilent/Keysight E1682A is a Synchronous Payload Envelope (SPE) Receiver module designed for VXIbus test systems. Operating as a message-based slave interface, the E1682A facilitates command execution and data exchange within modular instrumentation architectures. This C-size, single-slot VXI module integrates into the 75000 series product line and participates in VXIbus backplane communication protocols, enabling coordinated operation alongside controllers and other instrument modules.

Technical Specifications

• Module Classification: VXI Module, C-size, 1-slot configuration


• Function: Synchronous Payload Envelope (SPE) Receiver


• Device Type: Message-based Slave Interface


• Series: 75000 Series


• Status: Obsolete

Key Features

• Message-based slave operation requiring a VXI controller or Slot 0 management card


• Direct VXIbus backplane interface for command and data communication


• Standard VXIbus protocol compliance for cross-manufacturer system integration


• Compact single-slot footprint for space-efficient mainframe deployment

Typical Applications The E1682A serves in modular test environments where SPE message-based communication is required. Applications include complex instrumentation setups involving multiple VXI modules coordinated through a central controller, particularly in systems requiring synchronized payload envelope reception and processing.

Compatibility & Integration The module operates within VXIbus (VMEbus Extensions for Instrumentation) systems, an open architecture standard supporting multi-vendor instrument integration. The E1682A functions as a slave device and requires a VXI mainframe with active controller capability. Compatibility extends to all VXI-compliant mainframes and controller modules that manage message-based device communication. Integration leverages standard VXIbus protocols, with optional support through SCPI command sets and VXIplug&play specifications where applicable.
