Upper Power Limit and Resolution
Table 9 shows the upper power limit and measurent resolution at various
power ranges. As can be seen the resolution decreases as the chosen
[Range] decreases. The resolution is always 40 dBm less than the chosen
[Range] value. The Upper Power Limit is always 3 dBm greater than the
chosen [Range] value.
