Agilent/Keysight 70843C – Lightwave Signal Analyzer Module

The Agilent/Keysight 70843C Lightwave Signal Analyzer Module is a high-performance instrument module engineered for precision signal analysis in optical communications testing. Operating across bit rates from 0.1 Gbps to 12.5 Gbps, it functions as an error performance analyzer, pattern generator, and error detector. The module integrates into the 71612C Bit Error Ratio measurement and analysis system and supports remote operation via HP-IB control.

– Technical Specifications

• Bit Rate Range: 0.1 Gbps to 12.5 Gbps
• Pattern Generator/Error Detector: PRBS patterns 2^7-1 to 2^31-1
• Transition Time: Less than 30 ps
• Jitter (data and data output): Less than 20 pspp
• Data Output Amplitude: 0.5V to 2Vpp
• Output Voltage Levels: High +1.5V to Low -3.5V
• Form Factor: Rackmount configuration

– Key Features

The module delivers fast transition times and minimal jitter performance essential for high-speed signal integrity verification. Programmable PRBS pattern support from 2^7-1 through 2^31-1 enables comprehensive pattern-based testing across diverse protocols and standards. Dual functionality as both pattern generator and error detector streamlines test setup and reduces hardware requirements for BER measurement campaigns.

– Typical Applications

Error performance analysis in optical and electrical bit-error-rate testing. Pattern generation for receiver sensitivity and eye-diagram measurements. Error detection in link validation and production test environments. Multi-protocol testing across telecom, datacom, and custom signal formats operating within the supported bit-rate window.

– Compatibility & Integration

The 70843C is designed as a core module within the 71612C Bit Error Ratio measurement and analysis system. It can be deployed as a standalone component or integrated into an HP MMS system II cabinet with PSU and control firmware for complete BERT, pattern generator, or error detector functionality. Remote operation via HP-IB allows integration into automated test environments and network-based measurement setups. Rackmount configuration with /1CM and /1CP options ensures flexible deployment in standard test racks.
