Advantest D3173 – Pulse Pattern Generator to 3GHz

The Advantest D3173 is a pulse pattern generator designed for testing and evaluating high-speed digital circuits and systems. Operating up to 3 GHz, it delivers precise control over pulse parameters and supports both pseudo-random bit sequence (PRBS) and programmable pattern generation. The instrument generates PRBS patterns with mark ratio variability from 1/8 to 7/8 (including 0/8 and 8/8), and programmable patterns up to 2^16 (65,536) bits. When integrated with the Advantest D3273 Error Detector, the D3173 enables comprehensive bit error rate (BER) analysis and includes an Auto Search function to optimize threshold level and phase delay settings. The instrument connects via BNC connectors for signal I/O and supports GPIB (IEEE 488.2) for remote control and system automation. Engineers and system integrators rely on the D3173 for validation and manufacturing of high-speed digital components, advanced communication transmission systems, and super high-speed devices.
