Connect the transmission line for the
antenna system to the output of the
coupler assembly or the Bandpass Filter.
If the optional trap filter is present in
your system, a BNC sample jack is
located on the trap filter and can be used
for test purpose.
3.4 AC Input
Once the chassis and output connections
are in place, the AC can be connected to
the transmitter. The AC Input to the
high power transmitter connects to the
terminal block mounted in the AC input
box located toward the rear, right side
near the top of the cabinet. Connect the
AC Input Line 1 to Line 1 on the terminal
block, the AC Input Line 2 to Line 2 on
the terminal block and the AC Input
Ground to Ground on the terminal block.
Refer to Table 3-1 at the beginning of
this chapter for typical AC Input and
Current requirements for Digital
Transmitters.
