Overview - SDH/PDH Transmission Analyzer

This advanced and handheld SDH/PDH transmission analyzer performs on-line and off-line tests of T1, E1, E2, E3, E4, DS1, DS3, STM-1 (155M), STM-4 (622M), and STM-16 (2.5G). Performance analysis conforms to G.821, G.826, G.828, G.829, ZM.2100 and M.2101 international standards. This SDH/PDH transmission analyzer is used for pulse mask analysis, overhead analysis, point analysis and anomaly/defect analysis as well as bit error rate (BER) testing. In addition, its various functions also include automatic tributary scanning, automatic protection switching (APS), and round trip delay measurement.

Key Features - SDH/PDH Transmission Analyzer

  • 10.4'' TFT LCD and touch screen, visible graphic display
  • Flexible, software-definition, simulated LED for current and historical error indication
  • Multiple tasks can be created and deleted dynamically and freely
  • Large capacity for recording bit error and alarm events; events can be displayed in charts and graphics
  • Offers external clock Tx & Rx interfaces
  • Test results can be saved as HTML or TXT format or exported to U-disk or PC for viewing and printing

Main Functions - SDH/PDH Transmission Analyzer

  • Bit Error Rate testing
  • Performance analysis according to international standards including G.821, G.826, G.828, G.829, M.2100 and M.2101
  • Anomaly/defect analysis: Tx-end transmits anomaly/defect events and Rx-end receives anomaly/defect events with record and statistics; recorded events can be displayed in chart or graphics and also support filter selection
  • Overhead testing: overhead emulating transmission and receiving analysis; two parts: general part (including J0/J1/J2/S1/V5/C2) and extended part (all the remaining overhead bytes except A1/A2, B1/B2/B3 )
  • Pointer monitoring: Generate and receive G.783 pointer and NDF pointer and display pointer value real-time with tabular and graphic
  • APS timing measurement: measure the network switchover time. Insert K1K2 sequence at Tx end, preset switching protection trigger condition; capture K1K2 bytes at Rx end and decode bytes meaning
  • Round trip delay measurement
  • Auto scan each tributary with the range optional
  • Timing and synchronization testing
  • Real-time optical power testing
  • TCM serial monitoring: insert and monitor SDH channel's abnormality and TCM message string
  • Remote operation on the instrument by connecting with PC

Applications - SDH/PDH Transmission Analyzer

  • Offline service test: remote loopback test
  • Offline service test: end-to-end test
  • Online test: through splitter and high-impedance jumper test
