SyncTester
is a truly portable solution with an internal
high stability Rubidium reference. This makes it ideal for field testing as it does
not require an external reference.
SyncTester is delivered with WinSTS, Oscilloquartz'
new Windows software. WinSTS offers a user-friendly
interface that makes testing easy. WinSTS
calculates measurement data automatically and displays MTIE and TDEV graphs while you watch.
This is in addition to displaying TIE, Average
Frequency and Allan Deviation graphs while the
measurement is taking place.
Graphs can be saved for later analysis or imported
directly into other Windows applications, greatly
simplifying report generation. |

Telecommunications
equipment manufacturers are now required to measure
the performance of SDH equipment using parameters
that were not specified by previous standards. MTIE
and TDEV are now recognised by ETSI and ITU-T as
the synchronisation quality parameters.
Essential tool for any telecommunications network
The Oscilloquartz SyncTester
provides an invaluable health check on the efficiency of connections to other networks,
locates weak spots and potential problems that may
affect the flow of traffic.
Together with WinSTS, the SyncTester enables network
managers to carry out network stability tests (long
and short term), to assess the quality of references
from other carriers and to characterise the performance
of network element clocks.
SyncTester has the
unique ability to measure output wander,
due to pointer patterns, over long periods of time
(e.g. days or weeks), relating to very low clock
offsets between SDH multiplexers. The unit can be
used in a number of different ways, either as a
portable unit or at a fixed point.
Typical applications
In figure 1, a 2.048MHz reference generated by SyncTester’s
internal reference is applied to the G.812 clock.
The outputs from the G.813 clocks are then measured
against SyncTester’s reference to determine
the transfer characteristics at each stage of the
SDH synchronisation reference chain.
Figure 2 shows the SyncTester used in a PDH environment
to assess the long term stability of the network.
The application in figure 3 is of interest to telecom
operators who derive synchronisation references
from other carriers, thus ensuring that these references
are suitable for their needs.

The
result is a higher quality service and greater
utilisation of capacity.
