EXT AGC: MAX PWR
Sets the AGC voltage for a receive signal level of -25.0 dBm. The
voltage range is 0.0 to 10.0V, in 0.5V steps.
Upon entry, the current external AGC voltage level is displayed.
Press [
$] or [%] to increment or decrement the AGC voltage level in
0.5V steps. Press [ENTER] to execute the change.
Note: For any receive signal level between -25.0 and -60.0 dBm, the
