The Keysight E1454A Pattern I/O Pod is a signal buffering accessory for the E1451A and E1452A Pattern I/O Modules, designed to extend measurement accuracy to devices under test located up to 2 meters away. Each pod buffers input and output signals for two of the four I/O ports, improving drive capability and reducing loading effects on DUT outputs.
## Technical Specifications
• Buffers input and output signals for two of four I/O ports per E1451A/E1452A module
• Extension range: up to 2 meters to DUT
• I/O connections: 8-pin ports
• Cable supplied: 2.1 meters
• Timing compensation: Programmable delay devices with calibration-based skew correction
• Configuration requirement: Two E1454A pods per E1451A or E1452A module
## Key Features
• Pin-to-pin skew compensation on pattern I/O lines using programmable delays and stored calibration constants
• Tri-state control inputs for flexible test system integration
• External clock inputs for synchronized operation
• Response pattern clock delay on timing module ensures correct timing alignment at the DUT
• Signal buffering improves output drive capability and minimizes input loading
## Typical Applications
The E1454A supports extended-distance pattern I/O testing where DUT separation from the main test module requires signal conditioning and timing compensation. Dual-pod configuration enables full I/O coverage across the E1451A/E1452A module’s four ports.
## Compatibility & Integration
• Designed for: Keysight/Agilent/HP E1451A and E1452A Pattern I/O Modules
• System: Keysight/Agilent/HP 75000 Series Model D20 Digital Functional Test System
• Status: Obsolete product with no direct replacement identified by manufacturer
