8.1.12. Operating Environment
Temperature range: -10 to +40 degrees Celsius (14
•
Relative air humidity: Up to 95% @ +35 degrees Celsius (95
•
Height above sea level: Up to 3050 m (10000 ft) without output deterioration.
•
8.2. Functions
8.2.1. Process of Matching of Antenna Impedance
Fully automated.
•
8.2.2. Modes of Tuning
Two modes: Full (basic cycle of user tuning) and Quick (restoring preset full tune settings from the non-
volatile memory).
8.2.3. Memory for the User Tune Settings
Integrated non-volatile memory, separate for all four antenna-selectivity types and outputs.
8.2.4. Types of Antenna Selectivity / Bandwidth
For fitting the width of frequency segments to the natural bandwidth of antennas, four antenna selectivity
types can be declared:
Sharp (narrow bandwidth): the width of frequency segments is approximately 0.25% of the
•
central frequency of the band;
Regular - used by default. The width of frequency segments is approximately 1% of the central
•
frequency of the band;
Wide (wide/broad-band). The width of frequency segments is approximately 4% of the central
•
frequency of the band;
Fixed - for the tuning to be valid, it requires coincidence of the operating frequency with
•
tolerance +/-4 kHz to the stored value.
8.2.5. Bypass and Use ATU Modes
In BYPASS mode all components of the matching network are excluded, allowing direct operation of
broadband antennas. The normal mode is USE ATU.
8.2.6. Overview of Tuning Settings
Method for overview of all tuning settings is provided. Also, provided is method for deletion of individual or
all tuning settings.
