Functions: | RFmxSpecAn_GetAttributeI32 |
Description: | Returns the index of the carrier that was used as the power reference to define the upper (positive) offset segment relative power. The reference carrier is the carrier that has an offset closest to the offset segment. Use 'offset(n)' as the selector string to read this result.
