TX PWR Monitoring Interface
The TX PWR voltage is a function of the selected transmit power level. This voltage ranges approximately
from 0 to 5V, with 0V corresponding to +5 dBm (3 milliwatts) and 5V corresponding to +20 dBm (100
milliwatts).
Front Panel LEDs
With the TRACER 4206 powered-on, the front panel LEDs provide visual information about the status of
the TRACER 4206 system. Table 1 provides a brief description of the front panel features, and Table 2
(continued on page 27) provides detailed information about the LEDs.
