17 | Keysight | N4960A Serial BERT 17 and 32 Gb/s - Data Sheet N4960A clock source/BERT controller jitter specifications Configuration Calibrated stress is added to Jitter Clock Output and the Jitter remote head port clock through one of two modulators: a high deviation, low frequency path, or a low deviation, high frequency path. The amplitude of any stress appearing on the front panel Jitter Clock Output will be 1/2 of the value appearing at the N4951A/B remote head pattern generator data output (if connected to the Jitter port).
