The Wandel & Goltermann PF-4 Bit Error Measuring Set is a high performance measuring instrument for determining bit, block and code errors to 140 Mbit/s on digital communications equipments (PCM). - Patterns: pseudorandom sequences and freely programmable, abbreviable digital word - New method of synchronisation for pseudorandom sequences. No sync-loss with error bursts of any length, bit-slip recognition - Measurement of bit, block, code and external errors - Error ratio measurements or error count in time intervals - Results evaluated according to error thresholds, error increment, and error-free intervals - Error analysis to CCITT Rec.
