I have been doing a pnoise analysis for a PLL . Looking into the Pnoise simulation profile I have found a tab
regarding thevalue for " Reference sideband" .What is the value that I should put while my "Maximum number of sidebands =7".
The reference sideband is needed to compute either input referred noise or noise figure. If you only require the output noise, you can set the input source on the form to "none", and then you won't have to fill this in.
If you do want either of these quantities, then this is to allow you to define the relationship between the desired signal path from the input to the output so that you can get the right gain used to divide the output noise, or compute the amount of noise caused by the input port at the output.
The number specified is to define the frequency translation, so for a given output frequency Fout, the input frequency would be |k*PSSfund+Fout| - or you can use the select from list to pick the right frequency.
So for example you are simulating a switch cap filter where the input and output frequencies are the same, it would be 0. For a down converting mixer it might be -1 and so on.

I'm busy doing my day job, and will take a look at this later today if I have time (or rather your other post).

I’m not sure I know what you mean. What does the log file look like? What do you see in the results browser?
This is probably one of those things that going to makes more sense so we can see what you’re doing.
Also, you appear not to have read the forum guidelines, because this post is on the end of an old thread (the forum guidelines ask you not to do this) and even worse it doesn't even seem to be related to your question.
