For Evaluating STM-64/OC-192 Jitter

The MP1777A is a measurement solution for jitter evaluation. It sup-

ports 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 tol-

erance, 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 aux-

iliary measuring instruments, jitter tolerance and jitter transfer char-

acteristics 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 auto-

matic jitter measurement and can be used with the MP1777A to con-

figure an automatic measurement system for jitter tolerance and jit-

ter transfer characteristics

∗1

∗1: Requires MS4630B Network Analyzer, MP1763C Pulse Pattern Generator

and MP1764C Error Detector for automatic measurement of jitter toler-

ance. 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 in-

stalled, 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, UI-

p, 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 mea-

surements 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 soft-

ware/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 in-

terfaces.
