Hewlett Packard HP 3789B DS3 Transmission Test Set Made in UK

Description: Hewlett Packard HP 3789B DS3 Transmission Test Set Made in UK The HP3789B DS3 Transmission Test Set offers comprehensive error measuring capability for the Digital Transmission hierarchy at DS3 level (44.736Mb/s). It allows on-line non-intrusive monitoring of live digital traffic in a PCM transmission system, and with DS3 data generation its applications also include commissioning, field trials, and maintenance of DS3 transmission terminals and link equipment.The unit is designed to monitor B3ZS coded data for bit, frame, parity, and code errors at DS3 level and to detect bit, frame, and CRC errors at DS1 level. With optional DS1 and DS3 jitter measurement, it provides comprehensive error and analytical real-time measurements to assess the performance of a transmission system. The HP3789B is microprocessor-based and is compatible with the Hewlett-Packard Interface Bus (HP-IB). (HP-IB is Hewlett-Packard's implementation of IEEE Standard 488-1978). It may also be controlled via an RS-232 port. Results can be logged to an external printer or either an internal printer or internal disc drive. The HP3789B enables live traffic to be monitored for framing errors at DS3, DS2, or DS1 levels by testing the F and M bit sequences within the incoming data. The B3ZS coded DS3 input data is checked for correct parity and to ensure it complies with the B3ZS coding rules. Bit errors are detected by comparison between a compatible 15-stage Quasi-random or 8-bit word pattern and the internally generated reference pattern. DS1 bit errors are detected in the selected digroup by comparison with a 20-stage Quasi-random or 8-bit word pattern. In addition, CRC error measurement is available with Fe (extended frame) DS1 framing. Condition:Power cord not included. Photos represent the exact item that will be shipped.
