产品名称：HP3784A
*G.821 error analysis at 704 kb/s, 2, 8, and 34 Mb/s
*Optional jitter measurement at 2, 8, and 34 Mb/s
*Clock synthesizer rates between 1 kb/s and 50 Mb/s
*Single key measurement setup using preset memory
The HP 3784A is a portable error performance/jitter test set, offering standard telecom interfaces at 704 kb/s, 2, 8, and 34 Mb/s. In addition it has binary TTL/ECL interfaces for measurements up to 50 Mb/s using internal clock synthesizer. The 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.
HP3784A是便携式误码特性/抖动测试仪，提供704Kb/s,2,8和34Mb/s的标准电信接口，用选件的DS1，DS1C，和DS2和DS3，以北美速率（North Amerian rates)取代标准速率。另外它具有用于高达50Mb/s测量的TTL/ECL接口，使用的内部时钟合成器。可以得到用于SONET的特殊选配件，以用于STS1，DS3，DS1C的误码和抖动测量。
HP3784A便于把测量与预置值、自动接收机装置和错误性能通过/失败门限值一起使用。自动抖动骗差和模板子程序用作快速***测试，达到CCITT极限值。直通数据方式能够把抖动附加到成帧信号，以用于解复用器抖动容限的测试。测量总结
错误分析：根据CCITT G.821进行所有测量
