Advantest D3285 – Error Detector, 500 Mbps to 10 Gps

The Advantest D3285 is a precision error detector for high-speed digital communication systems operating from 500 Mbps to 10 Gbps. This instrument measures bit error rate, error count, error seconds, error-free seconds, and frequencies to verify signal integrity across data links and communication devices. It detects both INSERT (0 to 1) and OMITT (1 to 0) errors, making it essential for R&D, manufacturing, and quality assurance environments where transmission reliability is critical.

– Technical Specifications

• Measurement Capabilities: Bit Error Rate (BER), Error Count, Error Seconds (ES), Error-Free Seconds (EFS), Frequencies
• Error Detection: INSERT (0 to 1) errors, OMITT (1 to 0) errors
• Display: Large green LED display
• Operating Temperature: 0 to 40°C
• Operating Humidity: 40 to 85%

– Key Features

• GPIB interface for remote control and data retrieval with OP (Output Interrogated Parameter) command support
• Master/slave functionality to coordinate patterns with compatible pulse pattern generators for error rate determination
• Auto-search function for optimal timing and voltage adjustment
• Data and clock monitoring outputs
• Designed for horizontal operation with 10 cm minimum clearance around air vents

– Typical Applications

The D3285 serves critical roles in characterizing digital communication links during development cycles, validating manufacturing processes, and performing quality assurance testing. Engineers use it to isolate transmission faults and establish baseline performance metrics for high-speed serial interfaces.

– Compatibility & Integration

The instrument integrates with Advantest pulse pattern generators such as the D3185 via master/slave functionality. GPIB connectivity enables automated test systems and remote monitoring in production environments. Horizontal mounting orientation and adequate ventilation are required for reliable operation.
