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
