Table: Power Leveling Commands (1 of 4) lists the output power leveling command mnemonic codes that include electing an RF output power level, leveling the CW output power, and turning the output power leveling off. In addition, commands are provided for the level offset and step attenuator decoupling functions.
RF Output Power Level Selection
The command, L1 calls up each of the preset (or previously set) output power levels. Each command causes its associated RF power level to be output and opens that power levels parameter for data entry. Each command will also deselect any other previously programmed power level and will turn off an active power level sweep.
Attenuator Decoupling
The attenuator decoupling function provides for decoupling of the step attenuator (if equipped) from the ALC system. The AT1 command decouples the step attenuator, the ATT(xx) command provides for setting the step attenuator value for 0 to 110 dB in 10 dB increments, and the AT0 command deselects the attenuator decoupling function.

Mnemonic Code
Function
AT0
Deselects step attenuator decoupling.
AT1
Selects step attenuator decoupling.
ATT(xx)
