The Advantest D3281 is an error detector module engineered for error performance testing in high-speed digital communication systems. It identifies and counts transmission errors with precision, enabling reliable assessment of data integrity across telecommunications and data communication networks. The D3281 integrates into Advantest’s error performance testing ecosystem alongside pulse pattern generators and transmission analyzers.
Technical Specifications
The D3281 measures error performance across multiple metrics: error rate, error count, error second (ES), error-free second (EFS), and frequency/frame (FREQ/FRAME) modes. Input amplitude ranges from 0.1 to 2 Vp-p. Threshold level setup spans -2.040 to +2.040 V, with typical input sensitivity of 40 mV. The detector supports PRBS test patterns and programmable patterns for comprehensive signal validation.
Error detection distinguishes between INSERT (0→1) and OMITT (1→0) errors separately. SDH/SONET frame synchronization capability suits system-level evaluation requirements.
