Table 4-2 RFL PWR CAL Values for All ZHD+ Transmitters
NOTE:
Tolerances for the values in above Table 4-2 are +/-10W. Also note, in some GUI
display menus power levels are shown in kW (Example: 80W will be displayed
as 0.08 kW).
The following is a description of each of the Calibration and A/D parameters. Values
used are for discussion purposes only. Generic formulas are in bold text. For
alignment purposes, use the actual numbers for your transmitter that are logged onto the
Factory Test Data. Table 4-1, and Table 4-2 below show default Factors for all ZHD+
transmitters. These may be used for the math calculations in the following section, to
determine approximate values for your transmitter.
4.8.2.1 DAC_APC_REF
DAC_APC_REF [HOME, MORE, CONFIGURATION C, B] is a counter (internal to
the micro), whose output will be between 0 and 900, that is controlled by the RAISE
and LOWER buttons on the front panel. RAISE increases the count and LOWER
decreases the count. This number is then D/A converted to get the APC_REF voltage
