Description – SDH/PDH Transmission Analyzer

This powerful transmission analyzer is both portable and easy to use. The analyzer’s compact architecture, large TFT LCD, touch screen, and reliability makes it the perfect tool for installing and troubleshooting E1, DS3, STM-1/OC-3, STM-4/OC-12, and STM-16/OC-48 lines (optional).

Highlights – SDH/PDH Transmission Analyzer

• Electrical interfaces for SDH/PDH: STM-1,E1,DS3; Optical interfaces for SDH/SONET: STM-1/OC-3,STM-4/OC-12,and STM-16/OC-48 (optional).Tx and Rx are completely independent
• 10.4” TFT LCD and Touch Screen
• Flexible, soft-definition, simulated LED for current and historical error indication
• Bit Error Rate testing
• Performance analysis according to international standards: G.821,G.826,G.828,G.829,M.2100,M.2101
• Anomaly/defect analysis: Insert an anomaly/defect at the transmit end and receive anomaly/defect at the sink end. Records received anomaly/defect stats which can be displayed as graphics or tables
• Overhead analysis: Generate and receive overhead including SOH and POH
• Pointer analysis: Generate and receiver G.783 pointer and NDF pointer and display pointer value real-time with tabular and graphic
• Automatic tributary sca;
• APS-measurement including Service Disruption;
• Round Trip Delay measurement
• E1 Pulse Mask Analysis
