Instruction Manual

Automatic limit testing of
Maximum Tolerable Wander, MTW
ITU-T G.823, G.824
The ANT-20SE tests the device under test for conformance to the
standard tolerance mask limits for maximum tolerable wander.
Measurement poinits . . ....... upto10Frequency/Amplitude values
Detection criteria .........................TSE(bit error), alarms
Frequency range .....................10mHz to 10 Hz, step 1 mHz
Amplitude range .................. 0.1to200000UI,step: 0.1 UI
The result of each measurement is shown in a table with an ªOKº or
ªFAILEDº message.
Accessory
Acterna TSR-37 DA 3700/00
Rubidium Timing Signal Reference
The TSR-37 is a powerful reference source to quickly measure and test
the synchronization quality of PDH/SDH/SONET digital networks.
MTIE and TDEV measurements for up to 1000 seconds can be easily
performed without a GPS reference. Coupled with the optional
GPS-FC, the range of observation time can be largely extended to meet
specific requirements.
Provides the reference clock for wander analysis using the ANT-20.
