Linrad should fill the bill.

Do a search for the SM5BSZ website

At his index page,   http://www.sm5bsz.com/update.htm

there is some recent work on phase noise.

Usable in Linux or windows. Not for the faint of heart, very capable,
very experimental, very flexible. Grab your saddle and hang on.....

If Spectrum Laboratory does not immediately satisfy the need, contact
