DTVLINK-T2 Operation Manual

1. General Introduction

DTVLINK-T2 is an ideal meter for DVB-T/T2 and DVB-C

signals testing, which is a new model with color screen

and high performance. It demodulates and accurately

measure the COFDM signals carried through the

terrestrial TV system. Also it supports main function of

CATV system measurement, including digital TV and

analog TV. This model can measure and display most

indexes of Digital TV (Channel Power, MER, BER,

Constellation Diagram); Analog TV(Single-frequency

Level, Carrier Level of Full Channels Spectrum, HUM).

Also DTVLINK-T2 can measure Frequency Spectrum

Scanning, Trunk Voltage and Battery Voltage.

DTVLINK-T2 has RS-232 port for communicating with

PC software –TOOLBOX which can manage and

analyze the testing result file.
