</p>
<h2 class="purpose">Purpose</h2>
<p class="body">
This function configures the leveling mode and the attenuation, enables or disables decoupling the step attenuator from the ALC. This function permits setting of the Reference Level DAC to control the ALC gain when in external power leveling mode.

Sets the leveling mode of the output power.

Valid Values:

AUMG369XB_LEVELING_MODE_INTERNAL - Internal (Default)

AUMG369XB_LEVELING_MODE_EXTERNAL_DETECTOR - External Dectector

AUMG369XB_LEVELING_MODE_POWER_METER - Power Meter

<tr>
<td class="paramName">decoupleEnabled</td>
<td class="paramDataType">ViBoolean</td>
<td>
<p class="body">
Selects or deselects ALC step attenuator decoupling.
<br/>
Valid Values:
<br/>
VI_FALSE - Deselect (Default)
<br/>
VI_TRUE - Select
<br/>
Notes:
<br/>
Selecting ALC step attenuator decoupling decouples the step attenuator (if equipped) from the ALC system. This permits separate setting the ALC level and step attenuator.
<br/>
Deselecting the ALC step attenuator decoupling returns the MG369XB to its normal (coupled) leveling mode. In this mode, when the desired power level is set, the correct combination of ALC level and step attenuator setting is determined by the instrument firmware.
