The Agilent/Keysight J4223A is a single-slot C-size VXI module that serves as the central processor for the SpectralBER System. It manages transmitter and receiver module control, aggregates measurement results from multiple receivers, and communicates with a control PC or workstation via SCPI commands through a Command Module.
Technical Specifications
• Form Factor: Single-slot, C-size VXI module
• Interface: SCPI command protocol via Command Module
• Self-Test: Power-on self-test included
• Driver Standard: HP J4223A Universal Instrument Driver conforming to VXIplug&play specification with VISA support for GPIB and VXI protocols
– Key Features
• Central processing capability for SpectralBER System operation
• Transmitter module management and receiver module control
• Data concentration from multiple receivers into single output stream
• Electromagnetic compliance to EN 55011:1991 (Group 1, Class A) and EN 50082-1:1992
• General Product Safety Directive 92/59/EEC compliance
• ESD performance per IEC 61000-4-2:1995
– Typical Applications
The J4223A enables BER testing of SONET and SDH network elements operating at 10 Gb/s and below, including optical add/drop multiplexers, optical translators, transponders, and multi-channel systems.
– Compatibility & Integration
Designed as the core processing module within the SpectralBER family. Related optical modules (J1422B, J4230A, J4231A, J4232A) are Class I laser products compliant with US FDA Standard 21 CFR Ch. 1 1040.10 and EN 60825-1 (1994). System EMC performance requires replacement of worn or damaged cables with identical specifications.
