NewsCaster VT2 Operation
M17-0002-01A Rev 0.0 51 User Manual
Mode (6)
The MODE key is used to select from the
following operating modes:
• Normal: Transmitter is active, with or
without a video (or composite) input
signal.
• Standby: Transmitter is in STANDBY
until switched to another mode.
Frequency synthesizer, however, is
locked on frequency.
• V. PRES STBY: This mode is only
selectable when input is set to VIDEO.
If no video is present, the transmitter
will switch to STANDBY after a two-
second delay (minimum). Use this mode
to remotely place the transmitter into
STBY when a video signal is removed.
If the Test Generator is installed, the
user may set Color Bars to be activated
rather than have the unit go into STBY.
(See Section 5.3.)
• V-BLK STBY: This mode is only
selectable when input is set to VIDEO.
If the camera is capped, or black video is
present at the video input (no vertical
interval signals present) the NewsCaster
VT2 will switch to Standby within 30
seconds. If the black video or black
burst is removed, the unit will switch to
Standby in 2 seconds. When the video
signal is reapplied, the unit will return to
Normal mode within 2 seconds. If the
TEST GEN function is installed, the user
may select Color Bars to be activated
rather than having the unit go into
STBY.
AUDIO (7)
The AUDIO quick key is used for basic FM
audio mode, line/AES selection and gain
changes. After the Audio Button is pressed,
the Audio options will appear. The user
must then select the desired audio channel.
Once the desired audio channel is selected,
the arrow keys are used to scroll through the
parameter list.
The gain or mode selection is made using
the left or right arrow keys and edited using
the standard editing procedure. Additional
audio channels are selected with the up and
down arrows. To edit sub-carrier frequency,
refer to Section 5.4.1.
Note: When changing the sub-carrier
frequency range, the values are altered by
highlighting the character and using the
arrow keys to increase or decrease the
value. To enter the value, move the cursor
to the “M” (last character) and press the
“ENT” Button.
The gain adjustment allows for ± 6 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:
P
dBm
+ Gain -18 = P
dBu
0.0 dBm = -18 dBu
