Model:SDH-1620L SDH/PDH Transmission Analyzer
Overview:
The SDH-1620L is an advanced and handheld SDH/PDH transmission analyzer, which integrates in-service monitoring and out of service testing of E1/E3/E4, DS1/DS3, and STM-1 into one package. Being highly affordable, easy-to-use and scalable, this powerful unit is ideal for installation and maintenance testing over the SDH/PDH transmission and access networks.
Functions:
o BERT: BERT test for PDH and SDH, directly and automatically compare the test results with standards.
o Error performance analysis: ITU-T G.821, G.826, G.828, G.829, M.2100, M.2101
o Anomaly and defect testing: Tx-end transmitting anomaly and defect events, Rx-end receiving anomaly and defect events with record and statistics. Recorded events can be displayed in tables or graphics with filtering.
o Overhead testing: Overhead emulating transmission and receiving analysis includes 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).
o Pointer monitoring: Generate G.783 pointer and NDF pointer. Display pointer value in real-time. Record pointer adjustment events (positive, negative and NDF).
o APS timing measurement: Measure the network switchover time.
o Round trip delay testing: Measure the signal transport time from Tx to Rx.
o Tributary scan: Auto scan each tributary with the range optional.
o Timing and synchronization testing: Frequency accuracy test. Pull-in range and pull-out range test.
o Real-time optical power testing.
o Voice monitoring: Able to select any channel of SDH/PDH.
Features:
o Easy operation: 10.4’’TFT touch screen, visible graphic display.
o Simulated indicators: For current and history alarm and error status. Indicator quantities and types can be automatically set based on tested signals and interface settings.
o Multi-task testing: Multiple tasks can be created and deleted dynamically and freely.
o Clock interfaces: External clock Tx & Rx interfaces.
o Events record: Large capacity for recording bit error and alarm events, Events can be displayed in tables or graphics with filtering.
o Data management: Test results may be saved as HTML or TXT format or exported to U-disk or PC for viewing and printing.
