The Agilent N4906B serial BERT is a general-purpose bit error ratio tester designed for testing high-speed digital communication components and systems. 150 Mb/s to 3.6 Gb/s (option 003) pattern generator and error detector (option 102: 150 Mb/s - 12.5 Gb/s). Fast eye mask measurement for pass/fail testing (option 101). < 50 mVpp input sensitivity. Fast bit synchronization on bursted pattern. Pattern generator: Pattern generation for PRBS or memory based patterns. Pre-defined for sonet/SDH frames and patterns for 10 GbE. Flexible levels addressing a broad range of technologies, e.g. ECL, PECL (3.3 V), LVDS, CML. < 25 ps (10%-90%) transition times for option 012. < 50 ps (10%-90%) transition times for option 003 using N4915A-001 transition time converter. Error detector: BER measurements. Automatic threshold alignment. Automatic sampling point alignment.
