The Agilent/Keysight E1330B is a B-size VXI module delivering four independent 8-bit digital I/O ports for industrial and laboratory applications requiring flexible data communication and digital control. Each port configures independently as input or output with selectable positive or negative true logic. The module supports multi-level data transmission—individual bits, bytes (8-bit), words (16-bit), and long words (32-bit)—enabling efficient interfacing across diverse digital device architectures.
Technical Specifications
B-size, 1-slot, register-based VXI module with four 8-bit digital ports. Each port includes three SCPI-controlled handshake lines: FLG (flag/data handshaking input), CTL (control/data handshaking output), and I/O (port status indicator). Three additional custom lines per port support peripheral functions: PIR (peripheral interrupt), /RES (peripheral reset), and STS (status). The module implements Release on Interrupt Acknowledge (ROAK) interrupt handling.
– Key Features
• Four independent 8-bit digital I/O ports, individually configurable for input or output
• Positive or negative true logic selection per port
• Multi-level data transmission: bits, bytes, words (16-bit), and long words (32-bit)
• Six handshake and control lines per port (three SCPI, three custom/interrupt)
• ROAK interrupt handling for plug-and-play driver support
• Register-based architecture optimized for direct backplane control
– Typical Applications
Digital control in automated test systems, industrial process monitoring, data acquisition gating, equipment synchronization, and interrupt-driven sensor interfacing.
– Compatibility & Integration
Compatible with Command Modules E1300A/E1301A, E1306A, and E1405A/B, E1406A. Supports direct backplane control via C-SCPI and ISCPI in SICL environments with plug-and-play driver compatibility. Adapts to C-size mainframes using the E1403C Adapter. Interfaces with industry-standard opto-isolator racks. User’s Manual, SCPI Programming Guide, Service Manual, and Datasheet available.
