4.5.3.6.2 HyperTrack
HyperTrack™ is an all
-digital antenna control protocol that offers many benefits in antenna tracking performance
and system operation. These benefits are too numerous and wide-ranging to describe fully here, but they include
improved tracking stability, range-based tracking bandwidth, ability to track through strong interfering signals,
rejection of incidental AM (e.g., from spinning test articles), and optimal multi-receiver tracking.
Enabling HyperTrack™ switches the AM back panel output to all
-digital mode. This mode requires a
HyperTrack™
-compatible ACU for proper operation and to take advantage of the performance improvements.
Disabling HyperTrack™ switches the AM back panel output to legacy analog AM mode.
Note, in a HyperTrack™
-equipped receiver, the Sync Detect digital status output is unavailable. Also, when
HyperTrack™ is enabled, the Lock Detect digital status output automatically becomes a copy of the HyperTrack™
digital output data. The lock detect output defaults to fixed 0 if the HyperTrack
™
back panel is present. Refer to the
Digital Status Output (DSO) command in the RDMS
™
