The HP 71603B error performance analyzer consists of pattern generator, synthesized clock source, and error detector modules configured in the HP 70000 modular measurement system (MMS). The HP 71603B covers the range from 100 Mb/s to 3 Gb/s and features automatic clock/data alignment for rapid set-up of the error detector. The HP 71603B makes BER measurements on waveforms badly distorted by noise, jitter, and intersymbol interference through the high resolution setting of decision threshold and phase adjustment. Also features the simultaneous counting of errored ones and errored zeros to locate the source of pattern-dependent errors. Error distribut ion is analyzed by counting errored and errorfree intervals between one second and one millisecond. Bit Rate: 100 Mb/s to 3 Gb/s. Patterns and Data Outputs: As for pattern generators. Data Input: 0.5 V to 2 V p-p amplitude. Decision Threshold Range: + 1 to - 3 V, resolution 1 m V. Termination Voltage: Selectable 0 V or - 2 V nominal. Clock/Data Delay: ± 1 ns; resolution 1 ps. Errors Detected: Errored ones, zeros, and all logic errors. Measurements: Error count, ratio, errored seconds, deci-seconds, centi-seconds, milliseconds and G.821 analysis.
