Description
Specifies the DUC prefilter gain. Reduce this value to prevent overflow in the DUC interpolation filters. Other gains on the NI-RFSG device are automatically adjusted to compensate for nonunity DUC prefilter gain. This attribute only applies to DUC-equipped RF signal generators. To set this attribute, the NI-RFSG device must be in the Configuration state. The units are expressed in dB.
The following table lists the behavior of this attribute on supported devices:
