Note This attribute is not supported if you are using an external LO.

You do not need to use a selector string if you want to configure this attribute for all signal instances. Specify the signal name in the selector string if you want to configure or read that signal instance. Refer to the Selector String topic for information about the string syntax.

The default value is 0.1.

Supported devices: PXIe-5644/5645/5646, PXIe-5663/5663E/5665/5668, PXIe-5830/5831/5832/5840/5841/5842
