Power Spectrum not available, at least one offset must be enabled.	Enable at least one offset to proceed.

Message
Enabled offsets cannot be measured with current input configuration. Change offset definition, disable offset, or change input configuration to support required frequency span.
Enabled carriers cannot be measured with current input configuration. Change carrier definition, disable carrier, or change input configuration to support required frequency span.
Carrier reference frequency cannot be measured with current input configuration. Change Carrier Reference Frequency or input configuration to support required frequency span.
