BERTScope® Bit Error Rate Tester

The Confidence of a BERT with the Insight of an Oscilloscope

The BERTScope Bit Error Rate Tester Series provides a new approach to signal integrity measurements of serial data systems. Perform bit error ratio detection more quickly, accurately and thoroughly by bridging eye diagram analysis with BER pattern generation. The BERTScope Bit Error Rate Tester Series enables you to easily isolate problematic bit and pattern sequences, then analyze further with seven types of advanced error analysis that deliver unprecedented statistical measurement depth.

Pattern Generation and Error Analysis, highspeed BER Measurements up to 28.6 Gb/sec.The combination of impairment modulation, signal generation and analysis in one instrument enables receiver BER compliance testing for today's 3rd Generation Serial and 100G standards like; IEEE802.3ba, OIF-CEI and 32GFC communications standards.
Integrated Stress Generator for stressed eye sensitivity (SRS) and jitter tolerance compliance testing.A test signal's data rate, applied stress, and data pattern can be changed on the fly, independent of each other; enabling a diverse set of signal variations for testing chipset/system sensitivity.
Integrated, BER correlated eye diagram analysis with pass/fail masks for PCI Express, USB, SATA and other communications standards.Enhances the debug experience unlike other BERT's by providing a familiar eye diagram of the test results to compare against a standards specific mask.
Error Location and BER contour analysis on PRBS 31 and other digital signals up to 28.6 Gb/sec.Provides a quick understanding of signal integrity in terms of BER. Error location provides detailed BER pattern sensitivities to speed up identification of deterministic vs. random BER errors.
Optional Jitter Map provides fast jitter decomposition, accurate stress calibration at the DUT input.Fast, effective method for determining long pattern PRBS31 jitter composition with triangulation. Graphical representation makes jitter analysis more thorough, yet simpler to follow.
Optional Digital Pre-emphasis Processor provides user controlled pre-emphasis on pattern generator supplied data.Enables testing with compliant signals for standards like OIF-CEI3.0, Infiniband EDR,  PCI Express, 10GBASE-KR, SATA, 40GBASE-KR4, 100GBASE-CAUI.
Optional Clock Recovery Units provide clock recovery up to 28.6 Gb/s.Enables compliant testing and accurate Eye Pattern Analysis for high-speed serial and communication system standards.
