Additional Features:
- G.821 error analysis at 704 kb/s, 2, 8, and 34 Mb/s
- Optional jitter generation and measurement at 2, 8, and 34 Mb/s
- Clock synthesizer for rates between 1 kb/s and 50 Mb/s
- Optional V.11 interfaces for testing X.21 leased circuits
- 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.
Applications
- Automated production of 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
The Agilent 3784A is a portable error performance/jitter test set, offering standard telecom interfaces at 704 kb/s, 2, 8 and 34 Mb/s, with the option of codirectional interfaces at 64 kb/s and V.11 interfaces for testing X.21 leased circuits. In addition, it has binary TTL/ECL interfaces for measurements up to 50 Mb/s, using the internal clock synthesizer.
The Agilent 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 toa structured signal for jitter tolerance testing of demultiplexers.
