Anritsu MP1777A 10 GHz Jitter Analyzer:
The Anritsu MP1777A 10 GHz Jitter Analyzer is the world-first measurement instrument that conforms to new ITU-T recommendation O.172 (SDH jitter measuring instrument standard) and supports jitter measurement at 10 Gbit/s. This jitter analyzer can be used in various applications such as development and production of STM-64/OC-192 transmission equipment and optical modules that are currently being installed in submarine transmission systems and mainland network lines.
Jitter Definition:
In a digital network, the symptom in which the noise and transmission pattern on the transmission line disturb the timing of signals to be transmitted and put pulse waveforms out of phase before and after the average position is called jitter or wander. There is no clear boundary between jitter and wander. However, generally, frequencies lower than a phase change frequency (phase modulation frequency) of 10 Hz are called wander frequencies. Frequencies higher than 10 Hz are called jitter frequencies.

Examples of Measurement
Example of Jitter Tolerance Measurement for STM-64/OC-192 Clock Recovery
This jitter tolerance measurement measures the jitter tolerance point at which an error occurs when a jitter-modulated data signal is input to an STM-64/OC-192 clock recovery module.
The MX177701A Jitter Performance Test Software enables use of a measurement method (jitter tolerance measurement) that finds and evaluates the jitter tolerance point. This software also enables use of a measurement method (jitter sweep measurement) that adds a preset jitter value to check only whether an error occurs. The former method (jitter tolerance measurement) is suitable for applications such as performance evaluation for a DUT in research and development departments. The latter method (jitter sweep measurement) is suitable for the applications such as shipment inspection during mass production of the DUT in manufacturing departments.
Example of Jitter Transfer Characteristics Measurement for STM-64/OC-192 Clock Recovery Module
This jitter transfer characteristics measurement measures to what extent a DUT attenuates the jitter component of a jitter-modulated data signal at each jitter frequency when a signal is input to an STM-64/OC-192 clock recovery module. The MX177701A Jitter Performance Test Software automatically controls the Anritsu MP1777A 10 GHz Jitter Analyzer and MS4630B Network Analyzer for the measurement. This software enables jitter transfer measurement at 55 points for only 100 seconds and is suitable for the applications in research and development departments and manufacturing and inspection departments
