Chapter 5. BERT Scan Measurements
Marcus Müller
Bit error ratio test scan measurements use the variable sample delay and threshold of a bit error ratio tester receiver to make signal integrity measurements: signal levels and margins, jitter, transitions times, and other parametric results that go far beyond a simple bit error ratio test. In this chapter, we introduce the basic concepts of bit error ratio scan measurements and then discuss the various types of scans in detail.
5.1. Basics of BERT Scan Measurements
During a bit error ratio measurement, the error detector of a bit error ratio tester takes a digital sample every bit period and compares ...
