The Keysight/Agilent/HP E1452A is a C-size, single-slot VXIbus register-based module that delivers pattern generation and real-time data acquisition for automated test systems. With 32 I/O pins organized into four independent 8-bit ports, the module supports bidirectional data transfer, independent port configuration for output, record, or real-time comparison modes, and programmatic or triggered tri-state control. Operating at up to 20 MHz pattern rate with an external clock source, the E1452A provides 64 KB of segmentable pattern memory per port, enabling flexible test sequence definition and execution.

– Key Features
• Four independent 8-bit ports enabling flexible test configuration
• Segmentable 64 KB pattern memory supports complex test sequences
• Dynamic tri-state control for real-time pin reconfiguration
• TTL/CMOS output levels with tight timing margins
• Sub-nanosecond skew specification ensures signal integrity across parallel pins
– Typical Applications
• Digital functional test of integrated circuits and modules
• Pattern-based data acquisition in production test environments
• Real-time comparison testing with programmable response logic
• Multi-pin synchronous digital stimulus and capture
– Compatibility & Integration
The E1452A integrates into VXIbus systems and functions as a terminating module in the Keysight 75000 Model D20 Digital Functional Test System, typically positioned after an E1450A Timing Module. The module requires an E1406A Command Module and SCPI driver for operation. Standalone use is supported when an external clock source is provided. The module pairs with HP E1454A Pattern I/O Pods for extended measurement accuracy.
