BERT 1B881 _ 1.6T High Speed Bit Error Rate Tester
PSS BERT1B881 is a high-speed bit error rate analyzer (BERT) specifically designed for multi-channel PAM4 and NRZ applications. Each channel supports data rates up to 106.25 GBaud, making it ideal for 1.6T / 800G module R&D and advanced testing scenarios.
The system adopts a multi-core high-speed connector for electrical signal transmission and features a modular design that allows independent extraction for near-end testing. It can also be optionally equipped with a BER analysis module with optical interfaces, which can replace the standard LCD display interface.
The transmitter includes a built-in pre-emphasis adjustment mode for optimizing PAM4 eye diagrams, while the receiver supports equalization (EQ) and forward error correction (FEC) functions, along with data and graphical analysis capabilities.
Features
- PAM4 Data Rate Support: 53.125 GBaud / 106.25 GBaud.
- Pattern Options: PRBS7/9/11/13/15/23/31/58, PRBS7~58Q, SSPRQ, and user-defined patterns.
- Transmitter: Supports pre-emphasis adjustment to optimize high-speed signal integrity.
- Receiver: Supports equalization, SNR testing, and eye diagram simulation and analysis.
- Built-in KP4 FEC: Enables symbol error distribution analysis.
- SRC Remote Interactive Control: Provides a user-friendly test software interface and GUI-based programmable control experience.
- Modular Design: The main unit and electrical interface module can be separated for flexible adaptation to various application scenarios.
- Optional Optical Interface Module: The electrical interface can be equipped with an optional optical BERT module, replacing the LCD display function and supporting quick plug-and-play module replacement.
