Enables or disables the automatic leveling control (ALC).
PXIe-5654 with PXIe-5696: If this property is enabled, the ALC is closed (closed-loop mode) and allows for better amplitude accuracy and wider amplitude dynamic range. If this property is disabled, the ALC is open (open-loop mode), which is ideal when using modulation. Disabling the ALC Control property also allows NI-RFSG to perform an automatic power search.
PXIe-5654: Disable is the only supported value for this device. The PXIe-5654 does not support the ALC when used as a stand-alone device.
Supported Devices: PXIe-5654/5654 with PXIe-5696
Default Values:
PXIe-5654: Disable
PXIe-5654 with PXIe-5696: Enable
