For STM-64/OC-192 Jitter Evaluation
The MP1777A is a measurement solution for jitter
evaluation. It supports both the STM-16/32/64 and
OC-48/96/192 bit rates. In addition to supporting
the bit rates of 2488.32, 4976.64, and 9953.28 MHz
four additional bit rates used in submarine cable
systems can be added as options.
The MP1777A can evaluate jitter characteristics,
including jitter tolerance, jitter transfer and output
jitter, which are parameters most commonly used to
evaluate digital lines.
The MX177701A Jitter Performance Test Software
(bundled with MP1777A) allows the MP1777A to be
controlled remotely from a controller. And when the
Jitter Performance Test Software is used together
with specified auxiliary measuring instruments,
jitter tolerance and jitter transfer characteristics can
be measured automatically.
•Conforms to O.172 Recommendations
The MP1777A meets the STM-64/OC-192 measurement
standards. It is compatible with bandwidths up to 80 MHz
and jitter modulation amplitudes up to 3200 UIp-p.

•Four Optional Series of Bit Rates
Current submarine cable systems add FEC (forward error
correction) to signals to enhance quality. The MP1777A can
also support two series of bit rates by adding Option 01
(2494.16, 4988.32, 9976.64 MHz), Option 02 (2666.0571,
5332.1142, 10664.2284 MHz), Option 04 (3062.3629,
6124.7259, 12249.4517 MHz) and Option 05 (3069, 6138,
12276 MHz).
•Automatic Jitter Measurement
The MX177701A Jitter Performance Test Software is used
for automatic jitter measurement and can be used with the
MP1777A to configure an automatic measurement system
for jitter tolerance and jitter transfer characteristics

Application Examples
•Jitter Generation
To generate jitter an external signal generator is required to
source a modulation signal. The MX177701A Jitter
Performance Test Software and a GPIB card are required for
automatic measurement. It is also possible to perform man-
ual measurements which does not require these items.

•Jitter Measurement
The MP1777A can measure the jitter of input signals directly
without using an external BPF. When Option 10 (High
Sensitive Input) is installed, it can measure the jitter of input
signals with amplitudes down to 150 mVp-p. In this case, it
can perform evaluation by direct device connection. The
MX177701A Jitter Performance Test Software and a GPIB
card are required for automatic measurement. Manual mea-
surement is also possible and the measurement results are
checked on the MP1777A screen. Furthermore, UIp-p,
UI+p, UI-p, and UIrms can also be measured.
By combining the MP9677B E/O and O/E Converter, the
MP1777A can measure the jitter measurement of optical
interfaces.
