2.2.1 Optional Dual RF Output and Dynamic Combiner Test Feature

Figure 2-7 illustrates the Dual RF Output and Dynamic Combiner Test Option. This option is a module designed
to attached to the rear of the PHTS108 as shown, with module I/O provided by the “D” connector Cable Harness
Assembly. The module provides 2 modulated RF outputs and the capability to select and automatically vary
the 2 RF (CH1 and CH2) signal levels (Fade Depth), vary the rate at which these differing levels are changing
(Fade Rate) and vary the phase relationship between these 2 RF signals (Phase Shift).

Changing the Fade depth, Fade Rate and Phase between these 2 RF outputs provides the ability to dynamically
test a pre-d Diversity Combiner in a dual channel telemetry receiver and ensure proper performance using a
simulated real-world mission scenario.
