ACP: Automatic Cross Poll. Value shown in the DW4000/Antenna Pointing utility, and the DW6000/4020 user interface.
Isolation: The transmitter isolation figure is a product derived from copol and crosspol values associated with your transmitter. This is not a user function, but is performed manually at the NOC - usually at the request of Advanced Tech Support. The isolation numbers postet are for reference only, to assist in those occasions if/when Advanced Tech Support assists you with upload problems. (see note #1),
These levels have to be met or exceeded for the NOC to keep your transmitter enabled. Limits may vary a few points depending on your location, transponder assignment, and weather conditions.
(Note #1) Not to be confused with the "isolation" number reported in the DW4000/Adapter Diagnostic Utility/Get System Status. If/when viewing the "Get System Status" use of the word "isolation", refer to the appropriate ACP number above.
