Listed here are the standards that are programmed into the HI-4460 Graphical
Readout, and are selectable in the Main menu. If a value, or formula, is not
shown in the table, the value is dependent on frequency and the electric or
magnetic field values. For example, there is no value in the first row or the first
table for power density. Use the following formulas to calculate them. For any
formula in the table containing Af@ in the tables, use the frequency in MHz,
unless noted otherwise.
