Configuration Options

Power Supply

GAOTek Data Transmission Analyzer and E1/T1 BER Tester supports two power supply modes, DC and battery, with a built-in large capacity rechargeable lithium battery for 8-hour long consecutive operation after being fully charged.

When using external power supply, the battery will charge automatically with the battery capacity shown on the right top corner of LCD at any moment. When using AC power, please use the AC charger accompanied, or the instrument will be damaged.

Self-Test

In order to guarantee a reliable test result, we suggest you to have a self-test according to the following steps each time before switching on for testing.

Operation Keys

Abbreviation

All tests can be done according to the key-operation on the screen. All of the abbreviations used are listed as following for your reference.

Interface Description

The above picture is the left interface diagram, in which BNC interfaces on both sides are G.703 E1 unbalanced interfaces with the impedance as 75Ω, L1-RX representing input of L1 and L1-TX representing output of L1; the middle interface is G.703 E1 balanced interface with the impedance as 120Ω(E1/G.703 64K) or 100Ω(T1) including input & output

The right interface, in which BNC interfaces on both sides are G.703 E1 unbalanced interfaces with the impedance as 75Ω, L2-RX representing input of L2 and L2-TX representing output of L2 the middle interface is a 10M/100M RJ45 network interface

The below diagram is the top interface diagram

Data Management System

 Through RJ-45 Network Interface, operation and data exchange can be available in the Data Management System.

Introduction

Data Management System can achieve all functions between Computer and BER communication.

Through Data Management System software, computer can extract all test data in the memorizer, and saved in the Hard Discs of computer. Standard interface for database is available, which help manage data.

It can emulate manual operation in the platform, control this instrument, and carry on all operation through Mouse.

Work Environment

A necessary Configuration is as follows,

 Connection

Through RJ-45 network interface, Data Transmission Analyzer and E1/T1 BER Tester connects PC directly.

 Record Operation

When  data  comes  in  memorizer,  you  can  click  “Read  Records”  to operate. The extracted records will display in the bars, to save it by click, or you can click “Exit” to exit the system.

EXCEL and TXT format are available for the storage.
