For any digital communications link, the ultimate measure of its physical layer performance is to determine whether the bits sent are received correctly while transmitting data. At times errors can happen within the system, especially if the medium over which the data is being transmitted is noisy, leading to a compromise in the integrity of transmission. Bit Error Rate (or Ratio, as it is more correctly called) measures this performance. Bit Error Rate Testers are a common feature in many test labs either as BER test measuring devices, or as test pattern sources for other measurements. Any data stream sent through the communication channel, both radio link and fiber optic, is compared with the original. Any data errors are logged and bit error rate is determined. Unlike other forms of testing devices, BERTS measure the full end-to-end performance of the system including the transmitter, receiver, and any medium between the two. In this way, BERTS test the performance as if the system was in actual operation rather than testing the parts separately. High speed BERTs are typically used in design and manufacturing of high-speed components and the early phases of design of boards and systems. Bit Error Rate Test Set (BER, BERT, BERTS) test devices typically comprise of pattern generators, error detectors, clock signal generators, digital communication analyzers, and electrical - optical and optical - electrical converters. Traditionally, BERTS have been associated with radio communication links. However, they are also applicable to fiber optics and Ethernet links. BERTS are used to test many high-speed digital interfaces such as - QPI, FB-DIMM, PCI Express®, SATA/ SAS USB, Thunderbolt, Display Port, HDMI, MHL, MIPI, UHS-II, Fiber Channel, XAUI/10GB Ethernet, CAUI/100 GbE, CEI, OTN, PON-OLTs, etc. TRS-RenTelco offers single and multi-channel Bit Error Rate Test Sets (BERTS) from leading brands such as Anritsu, Keysight, Teledyne LeCroy, and Tektronix.
