When working with 112 Gbaud rates or higher, your internal error counter functionality may not be adequate for traditional BER measurements. Luckily, Keysight offers a new method to address this issue by using a high-speed real-time oscilloscope to capture the digital signal, determine BER through software decoding, and compare it with the expected pattern. With the introduction of PAM4 signaling and FEC, the raw BER targets of 112 Gbps links are now in the range of 2.4E-4 (optical) to 1E-5 or 1E-6 (electrical), making the real-time oscilloscope BER measurement achievable.

The Keysight Infiniium UXR-series oscilloscope is an example of this new method, with up to 110 GHz bandwidth, configured as a real-time error detector (RED) with the M8070B BERT control software. This speed improvement dramatically decreases the time required for engineers to successfully debug their device under test.

 The oscilloscope captures and converts the incoming signal into digital form, and these bits are sent over USB/LAN to a controlling PC running the BERT control software, which compares this data against the expected pattern to generate a BER measurement. The M8070B software also handles all necessary setup and control of the real-time oscilloscope. The pattern generator, which can either be a BERT PG (e.g., M8050A) or an AWG (e.g., M8199B), provides flexibility in terms of transmitter equalization (de-emphasis capabilities, raised cosine filtering, error insertion, etc.) The real-time oscilloscope offers high sensitivity, flexible clock recovery, and enhanced automated receiver equalization capabilities such as FFE, DFE, CTLE. This solution can handle multiple modulation formats such as NRZ, PAM4, PAM6, PAM8, and data rates up to 240 Gbps (120 GBd).
