hi, all
here are some questions about the spec of Tracking generator. could you somebody give me a guidance of the spec understanding and testing(verification method)?
1. RF power-off residual
2. why Danamic range spec defined as "Maximun output power level- Displayed average noise level" but "Maximum output power level- noise floor"?
your feedback is appreciated!

I just noticed this old post with no reply and thought I'd give you my best answer in case you were still interested.
A1) The RF power-off residual spec simply indicates the largest residual you can expect to see without the tracking generator RF signal being on
A2) The Dynamic range spec is defined as "maximum output power level- displayed average noise level" instead of "maximum output power level- noise floor" because of the instrument's ability to measure small signals is affected by more than just the noise introduced by the RF portions of the system. The displayed average noise level (DANL) of the instrument is dependent on the on various settings of the instrument. For example the DANL is highly dependent on the resolution bandwidth being used and this is important because it means the smallest detectable signal that the instrument can display depends on instrument settings which can be changed, and not just the "noise floor".
All of that being said, what I call DANL may be the same thing you call "noise floor" in which case there would be no difference.
Best regards,
