T-MOD ISDB-T/TB
A signal generator
Description
The T-MOD ISDB-T/TB is a cost effective ISDB-T (Japanese DTV standard) and ISDB-T/TB
(Brazilian DTV standard) modulator for adressing the Test and Measurement market. It
provides the opportunity for R&D laboratories and manufacturers to test their own product
ranges addressing in particular the emergent digital TV market in Brazil. More widely,
T-MOD ISDB-T/TB addresses the applications and needs of all players in the R&D laboratories
and manufacturers who need test signals.
Performant & Future proof
T-MOD ISDB-T/TB includes all the state-of-the-art technological features for ISDB-T/ISDB-TB
modulation. It has been specially developed to provide test solutions for equipment designers,
R&D laboratories designers, with a best of class performances and to exhibit a high
MER value, excellent shoulder levels and lowest phase noise. It includes all the necessary
clock and synchronization mechanisms required to operate Single Frequency mode (SFN).
A comprehensive & intuitive control software suite is provided to configure and control the
unit via RS232 connection. T-MOD ISDB-T/TB consists of a standalone modulator in 1U Rack,
with standard interfaces (ASI). It is capable of delivering a RF signal output over a wide
frequency band from 100 MHz up to 900 MHz.
