Need spreadsheet for system spur analysis

Hi,

Has anyone a suitable excel spreadsheet template for system spur analysis? I would need to take into account tunable LO, RF, IF, reference frequency and system clocks. It would help if someone could provide me such spreadsheet template. Anyway, I guess the analysis is quite straightforward fspur= ±NxLO±MxIF±OxFREF±PxSysCLK

Can anyone help me?

Of course it is quite difficult to estimate spur levels with spreadsheet analysis. But at least one could see the spurious frequencies

Kirt used to have some stuff on his website (rfcafe.com).

For this sort of work I've typically used Spectrasys from agilent/eagleware -- you can setup your block diagram and have all of the LO and IF frequencies determined by simple equations you write. This is really handy if you're trying to come up with "clever" spur mitigation techniques.
