Jitter and Wander

Automatic Measurement with Easy-to-Understand

Graphs

Jitter tolerance, jitter transfer and jitter frequency can all be

measured automatically. And since the data can be saved to

floppy disk in the text format, data management is made simple

by using a personal computer.

Masks conforming to ITU-T Rec. G.823/G.824/G.825/G.958 are

provided as preset data. Measurement is performed simply by

pressing the start key. Furthermore, the operator can also set

any other mask as necessary.

Jitter transfer measurement that is able to set

the selective bandwidth

In jitter standard such as ITU-T, ANSI, Bellcore, and ETSI, the

bandwidth selective regulation is still unclear for jitter transfer

measurement evaluation. This equipment selects the band-

width selection at the jitter transfer measurement in the range

of 1 to 30 Hz. It responds immediately when the standard such

as ITU-T, is reconsidered.

Mapping Jitter Measurement Method

Mapping jitter can be measured just by making a simple con-

nection with the MP1570A.

MP1570A

1.5 MHz/1.5 Mbit/s signal

2 MHz/2 Mbit/s signal

2/34/139/1.5/45M

SDHADM ADM

Extended jitter quantity and frequency shift monitoring

Able to measure jitter/wander and error/alarm at the same time,

so that the relationship of error/alarm generation and jitter can

be analyzed.

Through jitter function (only SONET/SDH)

Able to generate the jitter by through, while monitoring the input

jitter quantity.

Input signal Output signal

Tx jitter

Variable filter

Jitter measurement bandwidth(Hz)

Variable-type jitter measurement filter based on DSP

(up to 622 Mbit/s jitter measurement)

Filters regulated by ITU-T G series, such as ITU-T

O.171/O.172, ANSI, Bellcore, and ETSI are available as preset

data. The user can set the setting value of the filter freely and

analyze the cause of jitter trouble.
