PL (TX Power Level)
This command applies to the XBee/XBee-PRO Zigbee RF Module.
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, the current temperature and the amount of voltage over the typical 3.3 V. If the input voltage is too high, the device resets.
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 +3 dBm output.
Parameter range
These parameters equate to the following settings for the XBee RF module (boost mode disabled):
| Setting | Power level |
|---|---|
| 0 | -5 dBm |
| 1 | -1 dBm |
| 2 | +1 dBm |
| 3 | +3 dBm |
| 4 | +5 dBm |
These parameters equate to the following settings for the XBee-PRO RF module (boost mode enabled):
| Setting | Power level |
|---|---|
| 0 | 0 dBm (approximate) |
| 1 | +12 dBm (approximate) |
| 2 | +14 dBm (approximate) |
| 3 | +16 dBm (approximate) |
| 4 | +18 dBM |
