RF:ALC Control Property

RF:ALC Control Property

Short Name: ALC Control

Property of niRFSG

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
