2. Access the RF GENERATOR screen and
set the Amplitude to -75 dBm.
3. Access the RX TEST screen. Notice that
the Amplitude changes back to -50 dBm.
2. Return to the RF GENERATOR screen.
The Amplitude is no longer where you set it
in step 2 (-75 dBm).
Since the RX TEST screen has priority control over this field, the RF GENERATOR screen’s
Amplitude setting changed when RX TEST was accessed.
