PL (TX Power Level)
Sets or displays the power level at which the device transmits conducted power.
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 -4 dBm.
The XBee-PRO SX requires the power supply to be above 3.3 V to ensure 30 dBm output power. The
following table shows the typical values over supply voltage. If using a USB interface board with an
XBee-PRO SX module, you must supply external DC power.
Power supply Output power @ PL = 3
3.3 to 3.6 V 30 dBm typical
3.0 V 29 dBm typical
2.6 V 27 dBm typical
Note The device generates heat during RF transmission. There is an additional ground pad on the
underside of the module that is used for heat dissipation. For more details, see PCB design and
manufacturing.
