NewsCaster VT2

1. DESCRIPTION

Nucomm's NewsCaster VT2 series is a two
box Digital and Analog ENG/OB Microwave
Transmitter System. The Mast Mounted
Microwave Transmitter is designed to operate
in any specified band in the 1.00 GHz to
15.5 GHz frequency range. Each unit is field
programmable and configurable to meet a
wide range of customer requirements.
The NewsCaster VT2 is a "split-box"
transmitter system, utilizing a rack-mounted
Control Unit (19" x 1RU, sometimes referred
to as the "IDU"), and a Mast Mounted
transmitter RF Head (or "ODU"). The two
are connected with a single IF cable (RG-6
coax, or optional Triax), which carries the 70
MHz IF, Control Data, and DC power. For
cases where an existing IF cable in the Nycoil
must be used, and cannot support the
diplexing of the DC power, the NewsCaster
VT2 can be fitted with an AUX Power output
to send the power via separate conductors.
The NewsCaster VT2 is fully integrated with
an Analog FM modulator, compliant super-
low delay MPEG 2 Encoder and Multimode
Digital Modulator. Available modulations
include FM (NTSC / PAL), COFDM, optional
single carrier QAM, and optional VSB. As
additional digital modulation formats become
available, the VT2 can easily be software
updated. This makes the VT2 Rev B
extremely flexible while greatly reducing
circuit complexity.
