Once communications are restored the system will clear the alarm indications and resume normal
operations.
6.8 PTD Value is Noisy
The PTD (UTC Offset) value will be much noisier when the 4380A is in the dynamic mode and during the
positioning period while in the AUTO mode.
Static position users should use the AUTO mode when the antenna position is unknown. After the
auto_hours has expired, the antenna position will be determined by the receiver and the 4380A
will switch to the fixed position mode. Once this happens, the PTD value will be significantly
quieter. Users should put the system in Manual positioning mode and save settings once AUTO
mode is complete in order to prevent AUTO mode from occurring after a power failure.
If the antenna position is known, users should put the system in Manual positioning mode and
enter the latitude, longitude, and altitude of the antenna.
Poor antenna location and/or multipath issues can cause instabilities, relocate the antenna to a
more suitable location.
