The Agilent/Keysight E1450A is a C-size, two-slot VXIbus timing module that provides precision timing and pattern generation control for automated digital test systems. It synchronizes complex stimulus and response sequences, delivers programmable marker outputs, and interfaces directly with Pattern I/O modules to orchestrate high-speed DUT testing with cycle-by-cycle parameter adjustment.
Technical Specifications
• Module Type: Register-based VXIbus timing module, C-size, two-slot form factor
• Maximum Clock Speed: 160 MHz
• Edge Placement Resolution: 6.25 ns
• Timing Cycles: Up to 256 cycles per pattern
• Pattern Clocks: 12 total—6 for stimulus, 6 for response
• Control Signals: Eight general-purpose signals for strobes and synchronization
• On-the-Fly Parameter Adjustment: Supported across all timing cycles
– Key Features
• Accepts triggers from VXIbus backplane, front panel SMB connectors, or DUT
• Programmable marker outputs via front panel SMB connectors or VXIbus trigger bus lines
• Implements bus wait states using end-of-ready function with ready input
• Supports the optional E1453 Timing Pod for extended cable runs up to 2.1 meters
• E1453 pod buffers 8 control signals and 10 Q-lines; includes trigger and ready line conditioning
• When E1453 is not deployed, control and Q-lines route through module pod connector; trigger and ready lines use SMB connectors
– Typical Applications
• High-speed digital device testing requiring precise edge timing
• Multi-pin DUT synchronization with independent stimulus and response paths
• Automated test equipment (ATE) systems using VXIbus architecture
• Applications requiring on-the-fly timing parameter updates during test execution
– Compatibility & Integration
The E1450A connects to up to 10 E1451A/E1452A Pattern I/O Modules per mainframe, enabling control of 960 pins total with sufficient power. In extended systems using the E1482 VXIbus Extender, one E1450A operates as master for up to 2 slave E1450A modules, supporting up to 30 Pattern I/O Modules across multiple mainframes. External synchronization with DUTs and other instrumentation is fully supported.
