This unit
The HP/Agilent 3785B is a microprocessor-controlled jitter generator and receiver for testing digital transmission systems up to DS-3 rates (34368 kb/s). This portable instrument generates and measures jitter on both data and clock signals while conforming to CCITT Recommendation O.171, making it essential for production, field installation, and maintenance of PCM/TDM systems across cable, radio, satellite, and fiber optic links.
Technical Specifications The 3785B operates on 100/120 VAC or 220/240 VAC ±10%, with total power consumption of 640 Watts. It has DC output capabilities of 0-32 Volts DC and 0-20 Amps. The instrument accommodates up to four internal bit rates and integrates with HP-IB for bus-controlled operation and automated measurement sequencing.
Key Features
Generates and measures jitter via internal crystal clock or externally applied data stream
Sinusoidal modulation provided by internal synthesizer with adjustable amplitude and frequency
Transient-free sweeping through programmed CCITT-shaped jitter tolerance masks
Built-in measurement filters compliant with CCITT Recommendations
Six distinct measurement types: absolute jitter amplitude in UI pk-pk, jitter peak (positive or negative), jitter hit count, jitter hit seconds count, jitter hit-free seconds count, and maximum absolute jitter amplitude held during gating period
Internal modulation frequencies displayed on front panel per CCITT Recommendation O.171
External modulating signal input capability
Ergonomic front panel layout with microprocessor control
Typical Applications Production testing and field verification of CEPT and Bell digital transmission terminal and link equipment. Maintenance of PCM/TDM systems deployed across diverse transmission media.
Compatibility & Integration Compatible with CEPT or Bell digital transmission terminal and link equipment up to the third level of the digital hierarchy (34368 kb/s or DS-3). Full HP-IB integration enables remote control and automated test sequences.
