5.4 REDUNDANT INTERFACE
The
Redundant Interface connections are made with a 26-pin circular connector mounted on
the AWMT enclosure. The connector location is shown in Figure 4 at page 21 and in Figure 5
at page 22. A redundant system cable is provided with the redundancy kit that provides the
interconnection between the two AWMT units and the waveguide switches.
5.5 RF OUTPUT MONITOR INTERFACE
This RF output sample port is located at the Mon connector, which is mounted on the AWMT
enclosure. The type of mounting connector is listed in
TABLE 2 at page 21 and the location is
shown in Figure 4 at page 21 and in Figure 5 at page 22. This interface is used for the
independent monitoring of the AWMT output before the isolator and the harmonic filter. A table
of the coupling factor versus the frequency is provided with each unit.
