RF interfacing commands
The following AT commands are RF interfacing commands.
PL (TX Power Level)
Sets or displays the power level at which the device transmits conducted power. Power levels are
approximate.
For XBee-PRO, PL= 4 is calibrated and the remaining power levels are approximate. The device
recalibrates its power setting every 15 seconds based on factory calibration settings and the current
temperature.
For XBee, PL = 4, PM = 1 is tested at the time of manufacturing. Other power levels are approximate.
On channel 26, transmitter power will not exceed -5 dBm.
Parameter range
0 - 4
The following table shows the TX power versus the PL setting.
XBee modules
PL setting PM setting Channel(s) TX power* (dBm)
4 1 11 to 25 8
4 0 11 to 25 5
3 1 11 to 25 6
3 0 11 to 25 3
2 1 11 to 25 4
2 0 11 to 25 1
1 1 11 to 25 2
1 0 11 to 25 -1
0 1 11 to 25 -2
0 0 11 to 25 -5
X 1 26 -5
X 0 26 -8
* Highest power level is tested during manufacturing. Other power levels are approximate.
