The Agilent / HP 3784A is a BER and jitter test set for manufacturing, commissioning, and maintaining network equipment operating at CEPT telecom interface rates of 704 kb/s, 2, 8, and 34 Mb/s. It has a clock synthesizer and TTL/ECL interfaces for general-purpose BER testing at any rate between 1 kb/s and 50 Mb/s and has optional jitter or 64 kb/s codirectional interfaces.

For network operators, the Agilent / HP 3784A performs error performance analysis during the installation and maintenance of digital transmission networks and monitors in-service error performance using line code error detection. Long-term measurements can be made unattended and the results logged to an external printer. Several ease-of-use features include measurement presets, automatic receiver set-up and pass/fail thresholds.

For digital equipment manufacturers, the Agilent / HP 3784A synthesized clock source and binary interfaces allow general-purpose error performance testing of any design that transports or stores digital data. For production test, the Agilent / HP 3784A can be rack-mounted and automated with HP-IB or RS-232-C remote control.

For manufacturers of telecommunications equipment, the Agilent / HP provides a wide range of test patterns and enables flexible frequency offset tests and testing at non-standard rates. The Agilent / HP 3784A provides fully automated jitter tolerance and transfer function measurements. The jitter analysis facility enables the correlation of jitter hits with error bursts. Through-data jitter modulation allows jitter to be added to a fully-framed test signal passing through the Agilent / HP 3784A for jitter tolerance testing of demultiplexers. The Agilent / HP 3784A with Option 002 can be paired with the Agilent / HP 3764A Digital Transmission Analyzer with Option 002 or 007 to provide complete error and jitter test capability for manufacturing applications up to 139 Mb/s.
