12.3 SyncE Wander Measurements
12.3.1 Setup
Clock Port:
Select the appropriate connector or port required to match reference clock interface. Available options depend on
test port configuration and rate. Converter cables may be required in certain cases.
Clock External:
Select the type of signal that matches reference clock signal to be used.
Save TIE to USB:
OFF/ ON
OFF
presents the current real time TIE measurements on screen only.
ON
sends real time TIE measurements to an attached USB memory, for further post analysis (refer to the MTIE and TDEV
Analysis section). This feature requires the MTIE and TDEV Post Analysis option.
Sampling Rate:
When Save TIE to USB is ON, this selection indicates how many samples per second are recorded and stored
in the USB memory stick.
Press the Start button to run the test. If Save TIE to USB is set to ON, the test set asks for a file name (keep this into account
when running time-sensitive tests).
Note: Do not remove the USB memory stick while the wander test is running.

12.3.2 Results
Current TIE:
Shows the last Time Interval Error (relative phase error) measured between the reference clock and the test signal.
Max TIE:
Records the maximum TIE value measured since the test was started.
Min TIE:
Records the minimum TIE value measured since the test was started.
MTIE:
Shows the maximum difference between TIE values measured since the test started (Max - Min)
Note: The wander tests will automatically stop if either of the signals used as reference clock or recovered clock (test signal)
have significant levels of impairments, are lost, or disconnected.
Press the Stop button to terminate the test. If Save TIE to USB is set to ON, then remove the USB memory stick from the test
set, bring it to a computer, and open it with the VeEX Wander Analysis PC software, for further MTIE, TDEV, and masks analysis
(refer to the MTIE and TDEV Analysis section).
Both, Wander Analysis and MTIE / TDEV Post Analysis are optional features.
