For Evaluating STM-64/OC-192 Jitter
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
two 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. When the
Jitter Performance Test Software is used together with specified auxiliary measuring instruments, jitter tolerance and jitter transfer characteristics can be measured automatically.
Functions
• Conforms to 0.172 new 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 (3062.2629, 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∗1.
∗1: Requires MS4630B Network Analyzer, MP1763C Pulse Pattern Generator
and MP1764C Error Detector for automatic measurement of jitter tolerance. Requires MS4630B Network Analyzer and MP1763C Pulse Pattern
Generator for automatic measurement of jitter transfer. Also requires
controller, MX177701A Jitter Performance Test Software, GPIB card, and
cables.
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 manual 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 measurement is also possible and the measurement results
are checked on the MP1777A screen. Furthermore, UIp-p, UI+p, UIp, and UIrms can also be measured.
By combining the MP9677B E/O, O/E converter, the MP1777A can
measure the jitter measurement of optical interfaces.
• Jitter tolerance measurement
By combining the O/E and E/O converters, the MP1777A can
measure the jitter tolerance of optical interfaces. The MX177701A
Jitter Performance Test Software and a GPIB card are required for
automatic measurement. It is also possible to perform manual measurements without these items.
• Measuring Jitter Transfer Characteristics
The MP1777A can evaluate jitter transfer characteristics up to 80
MHz in applications such as 10 Gbit/s clock recovery module (O/E
converter) evaluation. Automatic (using MX177701A external software/GPIB) and manual measurements are possible.
By combining the MP9677B E/O, O/E converter, the MP1777A can
evaluate the jitter transfer characteristics up to 80 MHz at optical interfaces.
