For Measuring CODECs

DIGITAL TRANSMISSION ANALYZER

ME3401A

STM/SONET ANALYZER

MP1560A

The ME3401A offers portability and easy operation and is ideal for

testing, evaluating, and monitoring DS-2, DS-1C, and DS-1 system

as well as the DS-3 system. This multifunctional instrument has five

error detection functions (bit, parity, frame, bipolar violation, and CRC-

6), seven measurement functions (error rate, error count, error sec-

onds, % error free seconds, threshold error seconds, error perfor-

mance data, and alarm seconds), jitter modulation and measurement

functions, and multiplexer test functions. These functions make the

ME3401A a powerful tool for commissioning, and production tests,

as well as for maintaining, and troubleshooting digital radios, fiber

optic systems, and digital multiplexers. In addition, live traffic perfor-

mance can be measured by using a wide input range, the frame error

detection function, the demultiplex function, and the built-in printer.

The printer outputs the measurement results and automatically

records the time, and contents when an error or alarm occurs. The re-

ceiver makes it easy to measure the error rate or error count distribu-

tion and error performance

The MP1560A STM/SONET Analyzer is an error analyzer for the

Network Node Interface (NNI) of the Synchronous Digital Hierarchy

(SDH). The MP1560A provides many useful functions for evaluating

equipment during design, manufacturing, and development and is

especially suited for evaluating the transmission characteristics of the

52, 100, and 156 Mb/s interfaces used in SDH equipment.

The transmitter and receiver are housed in one frame and optical in-

terfaces (plug-in unit) are provided. In addition to functions for setting

and storing 64 frames of data in memory (option 01), a PTA controller

function (option 03/04) and 28-channel (maximum) simultaneous

measurement function (option 02) can be built-in.

Features

•

Meets mappings for ITU-T (Europe), SONET (North America), and

Japan

•

Can be used to analyze a variety of signal sources: optical (1.31/

1.55 µm), unipolar, CMI, B3ZS (52 Mb/s), AMI (100 Mb/s)

•

Many measurement items and functions for inserting alarms and

errors

•

OH byte can be set and monitored

•

ADD and DROP for 1.5 Mb/s, 2 Mb/s, 64 kb/s, 192 kb/s, 576 kb/s

•

Built-in floppy disk drive

OPTION

PCM CODEC ANALYZER

MS369B

The MS369B uses new technology to measure the characteristics of

PCM CODECs (Coder, Decoder). Single-channel CODECs (SCC)

are already being produced by many semiconductor makers for PCM

terminal equipment, digital exchanges, PBX, digital telephones, and

so on. The number of SCCs in use is increasing gradually. In addition,

former common-channel CODECs used time sharing among a num-

ber of channels. Measuring the characteristics of one single channel

make it possible to dispense with measurement of the other common

channels. For equipment using SCCs, however, the encoding and

decoding characteristics for each channel must be measured. As a

result, more channels must be measured which will lead to demands

for improved measuring performance.

The MS369B uses DSP (Digital Signal Processing) technology to re-

duce measuring time and to improve measuring accuracy. It also incor-

porates a high-performance, special-purpose LSI developed by

Anritsu. The MS369B reduces measuring time and automates mea-

surement using GPIB, and increases production and maintenance

efficiency.

Features

•

Both A-law and µ-law measurement

•

A-A, D-A, A-D, and D-D measurement
