HP 3784A is easy to use with measurement presets, automatic receiver setup and error performance pass/fail thresholds. Automatic jitter tolerance and transfer plotting routines are provided for fast accurate testing up to and beyond CCITT limits. Through-data mode allows jitter to be added to a structured signal for jitter tolerance testing of demultiplexers.

APPLICATIONS

Automated production test of transmission line and terminal equipment
Development and test of digital circuits that transport or store data
Long-term monitoring of digital transmission equipment in the field

SPECIAL OPTIONS

Special versions of the HP 3784A digital transmission analyzer offer error and jitter measurements at North American and binary interfaces, using unframed data. They provide all the features of the standard instrument with North American data rates, DS1 (1.544 Mb/s), DS1C (3.152 Mb/s), DS2 (6.312 Mb/s) and DS3 (44.736 Mb/s), replacing the European data rates. Another version offers STS1 (51.84 Mb/s) for testing SONET equipment.

Automatic and manual jitter measurements offer a fast, accurate means of characterizing digital transmission equipment. In addition, jitter can be added to any standard data signal passing through the instrument to allow testing of demultiplexers with a framed signal.

MEASUREMENT SUMMARY

Error Analysis	Error count, error ratio, error and error-free intervals (seconds and deciseconds), percent unavailability, percent errored and percent severely-errored seconds, percent degraded minutes. All measurements are made simultaneously.
Jitter Analysis	Peak-to-peak amplitude, jitter-hit count, jitter-hit and hit-free seconds or deciseconds.
