The Agilent/Keysight 69423A is a low-level analog-to-digital converter classified as obsolete but fully supported by Keysight. Though discontinued, this instrument remains available for repair, calibration, and technical support through Keysight Service Centers and the Contact Center via phone or email. Self-support resources are accessible through the Keysight website. No direct replacement product has been identified for this legacy converter.
Technical Specifications
The 69423A operates as part of Keysight’s multiprogrammer ecosystem. Related multiprogrammer platforms integrate HP-IB (Hewlett-Packard Interface Bus) connectivity, conforming to IEEE Standard 488 and ANSI Standard MC 1.1 for controller communication. Data and status readback leverage extended bus addressing features native to the HP-IB protocol.
– Key Features
• Low-level A/D conversion capability
• HP-IB interface for system integration and remote operation
• Mnemonic, action-oriented programming instructions supporting flexible configuration
• Internal microprocessor automatically detects card type and converts data to proper format
• Compatible with multiprogrammer architectures supporting real-time clock functionality (65,534 day range, 0.1 second resolution)
• Clock synchronization to detected power line frequency (50 Hz or 60 Hz)
• Parallel operation monitoring with interrupt capability on alarm conditions or process completion
– Typical Applications
The 69423A serves measurement and control applications requiring low-level analog-to-digital conversion within automated test and instrumentation systems. It integrates into multiprogrammer-based architectures for simultaneous multi-process control and monitoring.
– Compatibility & Integration
The 69423A interfaces with HP-IB compatible controllers. Related multiprogrammer support extends to HP Series 80, Series 200, Series 1000, 9825, and 9845 computers. Documentation packages including user guides with programming examples, utility programs, and operating/service manuals are available for supported computer platforms.
