5. OPERATION
5.1 FRONT PANEL OPERATIONS
On each screen, a cursor appears as an
underscore character, and is moved (6) or
(9) by the arrow keys. When the cursor is
under a desired item, select it by pressing ENT
and the underscore becomes a solid box. Use
(1s) or (if) to scroll the available screens
When the desired setting has been made, press
ENT to save the entry and put any change(s)
into effect. IfENT is not pressed, and the
keypad is left idle for 15 seconds, the changes
are discarded. in a multi-digit selection, as in
sub—carrier frequency, the boxed “Enter"
cursor can be moved left or right to select
other digits. Figure 25 and Figure 26 shows
the Menu Tree.
Standard Screen:
The Standard Screen appears at power up, and
displays channel, band, frequency, and output
power. Note the cursor under the channel
number.
CH=1 6,887.500MH2
BAND=6-7G HIGH 0.0dBm E]
Channel Selection:
Change channels on the Standard Screen by
underscoring the channel and pressing ENT to
select it. Use the up or down arrows to select
the new channel, then Press ENT to have the
new channel take affect. The unit will go to
standby as the synthesizer changes frequency.
Transmission will resume when the new
fiequency is reached.
Power Adjustment:
The power made of the NewsCaster VT2 is set
automatically to ANALOG or DIGITAL,
based on the Modulation (13) selected on the
M17-0002-00A Rev 4 51
front panel. This should not be confused with
the power 014mm.
The user can select HI or LOW power output
(change: the output level 3 to ddBm) by
pressing the I—H/LO button (13). The power
will change when the arrow button is released
The new value displayed is the current power.
CH=1 6,887.500MHZ
BAND=6-7G LOW 0.0dBm E]
Frequency Direct:
This is an optional operating mode allowing
the frequency to be changed without limitation
to channels. To use, move the cursor to
underline the fi'equency, and press the ENT
key. Use the left and right arrows to select the
digit(s) to edit, and the up and down arrows to
change the value(s). Continue this procedure
until the entire frequency has been set. When
complete, press ENT to have the new
frequency take effect. Ifthe frequency
entered is outside the band of operation, the
entry will be discarded, and an error message
showing the valid region of operation will be
displayed. In this mode the channel number is
replaced with asterisks “****”r To return to
channel mode, select the channel with the
cursor and change it to the desired channel
number.

The gain or mode selection is made using
the lefi or right arrow keys and edited using
the standard editing procedure. Additional
audio sub-carriers are selected with the up
and down arrows. To edit sub-carrier
frequency, refer to Settings in Section 5A.
The gain adjustment allows for 16 dB of
gain, and can be used to compensate for
variance in line levels. Audio levels will be
expressed in dBm when using analog
modulation and in dBu when in digital, per
the following:
P43“, + Gain -18 = P13“
0.0 dBm= -18 dBu
Lf LENE is selected, the unit accepts
balanced 600-Ohm inputs at +8 dBm
Analog (-10 dBu Digital). At 1 KHz input,
headroom is +18 dBm Analog (0. 0 dBu
Digital).
If AES is selected, the unit accepts data
fiom the backplane AES port(s) and decodes
the Group 1 audio from the SDI stream. If
only two audio channels are configured,
they will be the first channel in Group 1.
Four LED’s indicate the status of the audio
channel:
GREEN: On and working - OK
GREEN Flashing: Over modulation.

When analog modulation is selected, the
input selections will be:
Composite - The signal applied at the
INPUT connector is routed through the
internal low pass filter to modulate the
output. Typically, this filter has a
bandwidth of about 4.0 MHz for NTSC
and 5.6 MHz for PAL. The NTSC filter
selectivity ensures the higher frequency
video components do not interfere with
the 4.33 MHz audio subcarrier
S_DI - SDI is converted to Composite via
an intemai circuit and then processed as
a Composite signal.
Baseband/FSK - In this mode, the
signal bypasses the internal video low
pass filter. The input bandwidth (about
10 MHZ) is sufficient to pass a complete
composite video plus audio sub~carriers.
If the audio sub-carriers are “ON” they

will appear summed into the baseband
Signal.
External 70 MHz FM - The input
bypasses the modulator, and is routed
directly to the heterodyne up—converter.
When digital modulation is selected, the
input selections will be:
Composite - In this mode the input
signal is passed through the MPEG
Encoder and convened to digital.
& - The Input is routed through the
MPEG Encoder.
External 70 MHz Digital - The input
bypasses the modulator, and routes to
the heterodyne up-converter.
éfl - Input bypasses the Encoder and
goes to the digital modulator. The ASI
rate must be at or below the maximum
digital modulation rate.
TEST GEN (9)
This key allows editing of the 16 character

5.4 NEXTEL BAS RELOCATION SETTINGS
For our US clients, the NewsCaster VTZ is designed so that when it’s time to switch over to the
“post-Nextel” 2GHz band plan you will only need to change one setting, on one screen.
To preset the unit for “pre-Nextel“ and “post-Nextel” operation, there are two groups of settings that
must be made: “A UDIO SUB-CARRIER FREQUENCY" and “CIMNNEL BANDWTDTH & BAND
PLAN". These are described below,\
5‘4.1Audlo Sub-Carrier Frequency
In this section you set your “pre-Nextel” and “post-Nextel” Audio Sub-Carrier (ASC) frequencies,
so that when you make the switchover they will be ready to go.
Start the ASC set-up procedure by making the following menu selections:
SETTINGS>MODULATORJENCODER>ANALOG>AUDIO
g SCI Insertion: (-20 to -40dBc)
2(17)/7/13:
2(12)1-7
2 12 8-10:
This brings up a screen similar to the one at right, with the
settings and selections as described below:
NOTE: Press “Up” & “Down " to scroll through the ASC ’s, and press “Left” & “Right” to scroll
through the available settings The settings for all ASC ’s are modified in the same fashion ASC#Z
is used as the example
2 1 /7/13 This setting controls the frequency for the selected Sub-Carrier when
operating in the “pre-Nextel” 2GHz band (USA), and also for all the other
frequency bands (Le. 7GHz or l3GHz). The possible range for this setting is
4.83M'Hz to 8.5MHz.
2112! 1-7 This setting controls the frequency for the selected Sub-Carrier when
operating in the “post-Nextel” ZGHz band (USA) on channels 1 through 7.
The possible range for this setting is 4.83MHZ to 542MHz
2112) 8-10 This setting controls the frequency for the selected Sub—Carrier when
operating in the “post-Nextel” 2GHz band (USA) on channels 8 through 10.

5.4.2 Channel Bandwidth And Band Plan
In this section you can set your “pre-Nextel” and "post-Nextel” Video Bandwidth Deviation, so
that when you make the switchover they will be ready to go.
Start this set-up procedure by making the following menu selections:
MEW>Settings>Options>Nextel
2GHz Freq Plan: 2G(J 7), ZG(1 2)
BW(2G(17)/7/13): 4MHz, 3Afl1z
BW(2G(12)8-10): 4MHz, 3MHz
This brings up the screen at right, with the settings
and selections as described below:
2GHz Frog Plan This setting controls the 2GHz Frequency Plan which will be
used by the radio. Select the 17MHz “pre-Nextel” bandplau by
choosing “ZG(17)”, or the IZMHZ “post—Nextel” bandplan by
choosing “2G(12)”4
BW12G112117/131 This setting controls your Video Deviation bandwidth when
operating in the “pre-Nextel” 2GHz band (USA), and also for all
the other frequency bands (i.e‘ 7GHz or 13GHz). The possible
selections are 3MHz or 4MHz.
BWiZGg 12) 8-10! This setting controls the Video Deviation bandwidth when
operating in the “post—Nextel” 2GHz band (USA) on channels 8
through 10. The possible selections are 3NIHZ or 4MHz
NOTE: Due to bandwidth limitations ofthe ‘luost-Nextel ” 2GHz bandplan, in “2G(12)” mode, the
Video Deviation bandwidth of 2GHz channels I through 7 is locked at 3Mqu
5.4.3 SWITCHOVER TO “POST-NEXTEL” SETTINGS
For our US clients, when your DMA switchover date arrives, assuming you have already set the unit
per the preceding guidelines, you will only need to take the following steps to put the radio on the
new “post~Nextel” settings:
Stay #1: Navigate to the following menu: Settings>0ptians>Nex1el
Steg #2: Change your “2GHz Freq Plan” setting from “2G(17)” to “2G(12)”
Steg #3: Dane!
