Configures the loop bandwidth of the reference PLL.
Note Setting this property to Narrow allows the PXIe-5653 to lock to a reference with worse phase noise than the PXIe-5653 and utilize the better phase noise of the PXIe-5653. Setting this property to Wide on the PXIe-5653 allows the reference PLL to lock to a better reference with better phase noise than the PXIe-5653 and utilize the better phase noise of the reference.
Supported Devices: PXIe-5653
Default Value: Narrow
