spurious level vs noise floor of the system

Hello everyone,
I need to know the difference between noise floor level and the spurs level of the system. I know the basic definition of these terms. Lets say if i want to reduce the spur level below -60dbc,than what will be the level of noise floor at this spur level.Is it possible to relate these two terms. Thanks

No, you cannot relate spur level to noise floor level, because generally they have different origins.
