HP / Agilent 71501D Jitter Analysis System

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.

– Technical Specifications

• Data rate range: 50 Mb/s to 12.5 Gb/s
• Intrinsic jitter: < 0.002 UI rms
• Jitter measurement: Random jitter (RJ) and deterministic jitter (DJ) decomposition
• Bandwidth compliance: 20 MHz and 80 MHz measurement paths
• Test rates: 2488 Mb/s or 9953 Mb/s for compliance verification

– Key Features

• Automatic jitter transfer and tolerance measurements when integrated with BERT
• Time and frequency domain jitter demodulation
• Eye-diagram analysis with extinction-ratio and mask testing (Option 005 software)
• Built-in standard masks for major SONET/SDH transmission rates
• Fourth-order Bessel-Thompson software filters and Eyeline mode for continuous trace display
• Pattern-dependent effects investigation and trace averaging for small signal detection

– Typical Applications

• Component-level jitter characterization
• Transmission system jitter analysis
• 10 Gigabit Ethernet optical compliance testing
• SONET/SDH/OTN standards compliance verification

– 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.
