Keysight (Agilent) N4903B 7 Gb/s / 12.5 Gb/s J-BERT High-Performance Serial BERT

The Agilent N4903B J-BERT high-performance serial BERT is the flagship of Agilent’s N4900 serial BERT series. It addresses the needs of R&D and validation teams who characterize serial I/O ports or ASICs up to 14.2 Gb/s. The data rate can be extended up to 28.4 Gb/s by adding a 2:1 multiplexer and demultiplexer with clock data recovery. Integrated and calibrated jitter sources for jitter tolerance measurements allow designers to characterize and prove compliance of their receiver’s jitter tolerance. The quick eye diagram allows a one-shot check for a valid signal. Due to the higher sampling depth of a BERT, the eye contour lines visualize the measured eye at a deeper BER level for more accurate results. Extrapolated eye contour lines display the eye opening for even lower BER levels, such as 10^-15, reducing the measurement time significantly. Specifications-pattern generator.

Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Bandwidth
Bandwidth is the difference between the upper and lower frequencies in a contiguous set of frequencies within which a fiber optic component, link or network will operate.

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

SDH
Synchronous Digital Hierarchy (SDH) is an international digital telecommunications network hierarchy which standardises transmission around the bit rate of 51.84 megabits per second, which is also called STS-1. Multiples of this bit rate comprise higher bit rate streams. Thus STS-3 is 3 times STS-1, STS-12 is 12 times STS-1, and so on. STS-3 is the lowest bit rate expected to carry ATM traffic, and is also referred to as STM-1 (Synchronous Transport Module-Level 1). The SDH specifies how payload data is framed and transported synchronously across optical fibre transmission links without requiring all the links and nodes to have the same synchronized clock for data transmission and recovery.
