測量及維護 M1X 多工器, PABXs 和 PCM 終端機系統 

MS371A/ A1 是一部用于數字基群傳輸的有許多測試功能的,全面的測試儀器。它可用來測量 :

(1) 話音編碼/解碼表現特性
(2) 幀定位/警報測試
(3) 比特,編碼和幀誤碼 
(4) 時間抖動 
(5) 信令等

安立公司的 MS371A/ A1擁有測量 PCM 系統所必需要大多數功能,它是一*測試量儀器, 可以提高測試效率。PCM 系統的話聲音編碼/解碼的測試需要更多的時間和工作量。MS371A/A1 可儲存所有測試順序步驟及參數,并可重復呼叫出來從而大大減小測量時間并提高效率。

它具有GPIB控制功能,與MS120A話路選抉器一起使用,可進行順序的30個話路測試。它還可將測試結果與參考數值進行比較,做出判斷并自動以"好"或"不好"來顯示結果。測量結果亦可以內置的打印機打印出來,如有所需可外接打印機打印測試結果報告。 

傳統的測試系統,其測試結果通過個人計算機或外置設備進行修改,但MS371A/ A1 可以在內部完成并印到外部打印機上。 

功能:

  • 自動測量 A-A, A-D, D-A 和 D-D (A:類比;D: 數位);
  • 幀定位/警報 測試 
  • 誤碼測試 
  • 時間抖動測量 
  • 信令測試 
  • GPIB 控制器 
  • 內置打印機

Measurement and Maintenance of M1X Multiplexers, PABXs and PCM Terminal Systems 

The MS371A/A1 is an overall measuring instrument with many measuring functions for digital primary hierarchy transmission. It can be used to measure:

(1) voice encode/decode performance characteristics
(2) frame alignment/alarm test
(3) bit, code, and frame errors
(4) timing jitter
(5) signalling, etc.

The Anritsu MS371A/A1 has most of the functions required to measure PCM systems. It is an all-purpose measuring instrument designed to improve measurement efficiency. Measurements of PCM voice encode/decode performance require much time and labor. The MS371A/ A1 stores the measurement sequence and parameters in its internal memory and makes automatic measurements to markedly improve efficiency. It has a GPIB control function, which will allow measurements of 30 channels in one sequence when combined with channel selector. It also compares the measured results to a reference value, judges them, and displays GOOD or NO GOOD automatically. The measured results can then be printed out on the built-in printer. Another special feature is that the report of the measured results can also be printed out an external printer.

In conventional measuring systems, the results are edited with a personal computer or some other external device. However, the MS371A/A1 performs this function internally and prints out to the external printer. This unique function can instantaneously prepare test performance sheets during installation and report the results of periodic maintenance without the need for manual or computer evaluation.

Features

  • Automatic measurement of A-A, A-D, D-A and D-D (A: analog, D: digital)
    This analyzer automatically measures most of the items in ITU-T Recommendations - G.712/713/714. The test sequence and parameters are stored internally, and new test sequences or parameters can be entered by the operator. Also, measurement can be done manually or via GPIB 
  • Frame alignment/alarm test
    Frame alignment and alarm tests stipulated in ITU-T Rec. G.704/ O.162 can be performed 
  • Error measurement
    Error rate, error count, error second, and % error-free second can be measured by detecting the bit, frame, and code errors 
  • Timing jitter measurement
    Jitter modulation is available. Also jitter amplitude and jitter immunity can be measured 
  • Signalling measurement
    Manipulation/monitoring of the signalling bit and E&M signalling distortion can be measured 
  • GPIB controller
    A GPIB controller function has been incorporated. One to thirty channels can be tested automatically and continuously through the channel selector 
  • Built-in printer
    Results are printed out by the built-in printer. In automatic measurement, all results can be printed out or the printout can be limited to results failing the evaluation 
  • External printer
    Test results from channels 1 to 30 can be edited according to measuring item and printed out. A report, such as a test performance sheet, can be prepared immediay after the completion of measurements
