Model: SDH-1620A SDH/PDH Transmission Analyzer

Overview:

The SDH-1620A is an advanced and handheld SDH/PDH transmission

analyzer, which integrates on-line and off-line test of STM-1(155M) and E1 (2M)

and tests of STM-4 (622M), STM-16(2.5G) 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:

BERT:

BERT test for PDH and SDH and error performance analysis per

   G821, G826, G828, G829, M2100 and (or) M2101; Directly and

   automatically compare the test results with standards.

Anomaly/defect testing:

Tx-end transmitting anomaly/defect events and Rx-end receiving anomaly/defect events with record and statistics; recorded events displayed in chart and/or graphics and supporting 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 G.783 pointer and NDF pointer; display pointer value in real-time; record pointer adjustment events (positive, negative and NDF)

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 testing:

measure the signal transport time from Tx to Rx; Max. Min. and average latency statistics; set threshold on latency result.

Tributary scan:

auto scan each tributary with the range optional

Timing and synchronization testing:

frequency accuracy test; pull-in range and pull-out range test

Real-time optical power testing

TCM serial monitoring:

insert and monitor SDH channel’s abnormality and TCM message string

Remote control:

remote operation on the instrument by connecting with PC

Operation lock:

set lock status and ensure the instrument’s normal work without outsider’s interference.

Features:

1. Easy operation: 10.4’’TFT touch screen, visible graphic display

2. 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.

3. Multi-task testing: multiple tasks can be created and deleted

dynamically and freely.

4. Clock interfaces: external clock Tx & Rx interfaces

5. Events record: large capacity for recording bit error and alarm events; events displayed in chart and graphics and supporting filter selection

6. Data management: test results may be saved as HTML or TXT    format or exported to U-disk or PC for viewing and printing
