The HP/Agilent 71501D Jitter Analysis System is a dedicated instrument for measuring jitter across signals from 50 Mb/s to 12.5 Gb/s. It delivers demodulated jitter signals in both time and frequency domains using advanced sampling techniques, characterizing random jitter (RJ), deterministic jitter (DJ), cycle-to-cycle jitter, data-dependent jitter (DDJ), intersymbol interference (ISI), duty cycle distortion (DCD), and total jitter (TJ) estimation. When paired with a BERT, the 71501D automatically measures jitter transfer and jitter tolerance to SONET/SDH/OTN standards.

– Compatibility & Integration
The 71501D requires clock source modules for operation, such as the 70311, and integrates with BERTs for combined jitter and bit-error measurements. It accepts personality cards including the 70874A eye-diagram analyzer personality and operates alongside other Agilent/HP test equipment platforms.
