66..1313 Sync TestSync Test
Sync Test application provides One Pulse Per Second (1PPS) measurement and One
Way Delay (OWD) measurement.
1PPS measurement measures phase difference between the 1PPS signal
under test and the reference 1PPS signal.
OWD measurement measures the time error of PTP packet against the
reference time obtained from GPS satellites.
Ground Master Clock, Boundary Clock, etc will be assumed as the device under test.
To perform Sync Test application, the MT1000A-005 and the MU100090A are
necessary.
Using the MU100090A allows you to perform 1PPS comparison and OWD measurement
based on GPS signal.
The connection between the MU100090A connectors and MT1000A connectors are
described in the following section:
GPS Disciplined Oscillator Interfaces
Click the GPS icon ( ) on Status bar， and set Sync. Mode to GPSGPS. When selecting

A connection example between the DUT and the Network Master is shown
below.
