Agilent / HP 37717A
The Agilent 37717A
is a multirate bit error measuring test set. It
can generate and receive a range of data pattern,
and provide analysis of receive errors to G821 requirements.
The jitter measurement module for the HP 37717A
PDH/SDH BER and jitter test set is the first in
a new generation of jitter measurement implementations.
To allow accurate measurement of jitter created
by the SDH network into the PDH network, the following
techniques have been employed.

oscillator (VCO) used to track the carrier frequency
signal being received has a bandwidth of 4 Hz. This
will provide a better reference for the measurement
of long transients produced by pointer activity.
Separate positive and negative peak detectors will
ensure that all spikes of jitter are captured irrespective
of when they occur within the measurement period.
The maximum peak-to-peak jitter displayed by the
instrument will be the difference between the positive
and negative peaks within the gating period, ie,
the use of fixed measurement periods within the
gating period will no longer be employed.
use of these techniques, the HP 37717A provides
a jitter tester that will give accurate measure
of jitter in a PDH signal, irrespective of the network
topology that the signal has passed through.
