Section 1 Introduction
Platinum VAX-C Series
1.8 Transmitter Accessories
The VAX-C chassis contains the basic VAX transmitter. Additional options are
available and may be present in a VAX-C transmitter system. In as much as these
accessories do not significantly change the functioning of the core transmitter itself, it is
understood that this manual addresses customized transmitter configurations that may
contain one or more of these options.
In the case of a relatively high level of customization, this manual may also be
accompanied by a supplemental “customer-special” manual. In the case where
conflicting information is presented in the two manuals, the information given by the
customer-special manual supersedes any information contained in this manual.
1.8.1 Rack Integration
VAX-C digital transmitters are purchased as an individual component (sometimes
referred to as stand alone models) and can be mounted in an equipment rack provided
by the customer. Harris can provide a complete rack integration package, including
filters and other RF components. The VAX-C needs to have rear support as the back of
the unit has the majority of the weight, adjustable rack rails can be provided by Harris to
support the VAX-C in a rack.
1.8.2 Directional Coupler or Wattmeter
Optional precision directional couplers are available. A through-line wattmeter capable
of measuring the output power directly may be supplied as another option. External
couplers are required to provide sample ports for test and monitoring equipment. An
additional directional coupler is required after the filter to provide a signal source for
RTAC operation.
