User Guide and Technical Manual
NewS
tream
has six separate frequency maps which are selected based on the state
of the radio and the type of ODU connected. There are six channel plan maps for ENG
and one additional one for Satellite. The Frequency Settings page allows the operator to
set or modify the list of channels for any frequency band.
The frequency map is partially determined by the type of the Outdoor Unit [ODU]
which is connected to the IDU. Each ODU supports different bands of operation. In the
Frequency setup, you are presented with drop-down menu that allows selection of any
of the frequency maps. You must select a speci
fi c frequency band to con fi gure. By
default, the list is populated by the industry standard frequencies that broadcasters use
for these bands. You can change the channels to represent these settings anyway that
you wish. The same frequency can be applied to multiple channels if you so choose.
There is no cross-checking mechanism within
NewS
tream
’s software to ensure that
each frequency is unique.
You can also add additional channels to the frequency mapping if more channels are
needed. The maximum number of channels in a frequency mapping is 22 separate
channels, each with (-), ( ), and (+) values, so that a total of 66 separate channels in a
frequency mapping are allowed.
Once you are fi nished changing channels to a frequency map, you must next save the
group of frequency maps to a frequency plan that includes a user-assigned name by
clicking the
Save
button.
You can create a speci fi c frequency plan for NewS
tream
as part of the con fi guration
cloning. For US-based systems, NewS
tream
contains a frequency plan that
broadcasters typically do not revise.
