Figure 52 shows the possible range values you can choose. These values range
from 10 dBm (upper power limit of 13 dBm) to −70 dBm (upper power limit of
−67 dBm) in 10 dBm increments.
Upper Power Limit and Resolution
Table 1 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.
