Method of operation
By performing the following operations, it is possible to observe on the
oscilloscope how the 10MHz output of the slave is phase-locked to the master
and the rises of 1pps are aligned with microsecond accuracy.
1
Complete the above connection. Next, 10MHz output and 1pps output are each
monitored with an oscilloscope.
1.1
Compare 10MHz with master and slave, and when trigger is applied to master,
slave signal flows to either right or left (frequency is different).
1.2
When 1pps is compared between the master and the slave, the rising position is
observed to be off by more than 1 microsecond.

How to phase lock the slave module clock to the master module clock
2.1
Press the “Lock” button on the Slave module
2.1.1
Then 10MHz will phase lock within a few seconds, and the slave signal is
observed to stop flowing.
2.1.2
After the 10MHz phase lock is observed, the rise of 1pps is alighned within 5
seconds with an accuracy of less than 1 microsecond.
2.2
Press the “Lock” button on the Slave module again to “Unlock”.

How to reset
3.1
Slave module reset
3.1.1
Press the “Reset” button on the Slave module.
