The 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 HP3784A 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 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 HP 3784A can be rack-mounted and automated with HP-IB or RS-232-C remote control.
For manufacturers of telecommunications equipment, the HP 3784A provides a wide range of test patterns and enables flexible frequency offset tests and testing at non-standard rates. The HP 3784A provides fully automated jitter tolerance and transfer function measurements for testing up to and beyond CCITT limits. 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 HP 3784A for jitter tolerance testing of demultiplexers.
