When the programmable External Attenuator is detected, the appearance of the menu display
updates accordingly:
Use the [
←][→] arrow keys to select the TX PWR MODE parameter (on the top line of the
display), then use the [
↑] [↓] arrow keys to select the Tx Power Mode. Selections may include:
Tx Power Mode Description
MANUAL
This is the normal power mode, with a calibrated Tx power level range of
–40 to 0dBm. Level values of –45 to 0 dBm are permitted; values noted with
* indicate when a level exceeds the specification. The External Attenuator
will be switched off, if present.
MANUAL-LOW
