SP-3000 measuring system
The SP-3000 measuring system is destined
for complex wander testing of timing and synchronization signals,
e.g. in digital telecommunication networks. The SP-3000 system was
designed at the Institute of Electronics and Telecommunications, Poznan
University of Technology. It is a highly updated version - as far
as both hardware and software are concerned - of the SP-2000 system,
installed in different telecommunication nodes all over Poland since
the year 1996. It replaces also the previously offered TIEM meter,
which is at present a 1- or 2-channel version of the SP-3000 system,
assembled in a smaller cassette. The present system, like the previous
one, enables the testing of the quality of clocks as well as the synchronization
quality of synchronization networks in relation to international,
national and operator-created standards. In the configuration with
rubidium oscillator, the SP-3000 is an autonomous system, i.e. it
contains all elements necessary to acquire the signal tested (the
probes) from working digital lines without transmission disturbance
and to perform measurements. It has an internal reference signal with
automatic or manual compensation of frequency changes observed in
the internal rubidium oscillator. It has also an appropriate software
for measurements and comparison of the results with international
standards. The SP-3000 system has been a unique world-class solution
so far, due to such features as:
From 1 to 4 independent measuring channels, performing
measurements for signals with the same or significantly different
nominal frequencies. For example, the parameters of 2048kHz signal
may be tested in relation to the 10MHz, 5 MHz, 2048kHz, lpps, or
Built-in source of reference signal for testing
the parameters of synchronization network with automatic (to external
2048kHz signal or lpps signal from external GPS receiver, optionally
to 5MHz, 10MHz or other signals) or manual compensation of frequency
changes in the internal rubidium oscillator, caused by ageing effects
of the oscillator.
The lack of frequency retrace error of internal
oscillator, due to the built-in power maintenance of the oscillator
during SP-3000 transportation.
Autonomous, active measuring probes for acquiring
the signals tested from working telecommunications lines without
disturbing or interrupting a data transmission.
Practically unlimited time of single measuring session,
depending only on the capacity of hard disks installed in Laptop
Reach software with unique procedures (certified
by respectable research publications) speeding up the calculations
of MTIE and TDEV even by thousands of times.
Built-in sets of 14 standards, a possibility of
defining further standards, including user standards.
Module structure, enabling the completing of system
cards, according to user's needs.
