UNPACKING & INSPECTION
Unpack the NewsCaster VT2 and visually

PRE-INSTALLATION
CHECKOUT
NOTE: The NEWSCASTER VT2 Control
Unit and RF Head conventionally are
connected with either a single TNC Coax or
Triax cable. In a typical system, +48 VDC is
fed to the RF Head through this cable along
with the 70 MHz IF and Control Data signals.
However, there is a distinct different between
the two types of cables. For the TNC Coax,
the signals are diplexed onto the center
conductor of the cable. For the Triax, the
signals are diplexed on the inner shield of the
cable.
WARNING!
DO NOT connect the wrong type cable
to the wrong type unit, since doing so
will damage one of the connectors and
result in intermittent failures.
M17-0002-01A Rev 0.0
Connect the NewsCaster VT2 IF output to the
RF Head via an appropriate IF cable. (Refer
to Table 7.) Connect the RF output of the RF
Head through a 30 Watt, 30 dB attenuator to a
spectrum analyzer and observe the output
frequency on the analyzer display. Note that
the frequency and level correspond directly to
the LCD display on the front panel of the
VT2.
NOTE: The power level displayed on the
LCD is for indication only.
