Agilent/Keysight E1306A

The Keysight E1306A is a B-size VXI GPIB command module engineered as an embedded controller for 20-slot E1302A mainframes. It bridges GPIB (IEEE-488) connectivity with VXI backplane communications, parsing SCPI measurement control commands and directing them to register-based VXI devices from any manufacturer. The module operates as the system resource manager and must occupy the first mainframe slot. It features an 8 MHz 68000 processor, up to 2 MB nonvolatile RAM (expandable in 1 MB increments), and RS-232 auxiliary connectivity for terminal and debug operations.

– Technical Specifications

Processor & Memory
• 8 MHz 68000 core processor
• Nonvolatile RAM: up to 2 MB, expandable in 1 MB increments
• Recommended additional RAM: 1 MB minimum; 2 MB for high-channel configurations (e.g., E1313A 32-Channel Scanning A/D)

Interfaces
• Primary: GPIB (IEEE-488)
• Auxiliary: RS-232 for terminal connection and debugging

Real-Time Clock
• Accuracy: 0.01% of elapsed time since last set ± 1 second
• Resolution: 1 second
• Battery life: 60 days typical (NiCad, approximately 1 year)

Triggering & Pulsing
• Trigger input: TTL compatible
• First pulse accuracy: 0.01% of programmed time + 600 to 850 ns
• Subsequent pulse accuracy: 0.01% of programmed time ± 50 ns
• Pulse count: 1 through 8,388,607 or continuous
• Minimum pulse width: 300 ns

Physical
• Form factor: B-size, 2-slot module
• Connector: P1
• Not adaptable to C-size mainframes

– Key Features

• Register-based VXI device commander with SCPI support (non-Compiled)
• Slot 0 resource manager capability—required first-slot placement
• Exclusive VME bus master operation; incompatible with VXLink and other bus-mastering modules
• Manufacturer-agnostic device access across register-based VXI ecosystem

– Compatibility & Integration

Designed specifically for Keysight E1302A 20-slot mainframes. Functionally identical command modules exist in E1300A mainframes. Access to any manufacturer’s register-based VXI devices supported.
