DTVLINK-T2 Operation Manual
Basic Functions Overview

1.1 Channel Measurement

DTVLINK-T2 supports accurate signal level test in
analogue TV, DVB-T/T2 signals and single frequency
modes.
For Analogue channels, you can get video level, audio
level and △ V/A etc.
For DVB-T channels, DTVLINK-T2 supports modulation
modes of QAM and QPSK. Here, you can get Channel
Power, MER and BER and Constellation Diagram.
NOTE: For DVB-T channels, MER and BER test is only in
QPSK and QAM(16/64QAM) Modulation Mode.
1.2 Constellation Diagram
For DVB-T channels, Constellation diagram function
supports modulation modes of 16QAM ,64QAM and
QPSK. Here, you can get Channel Power, MER, CBER,
VBER, CARRIER and Constellation diagram.
1.3 Tilt/Level List
Tilt/Level list test is the effective solution to check the
flatness and amplitude, and DTVLINK-T2 support 12
