Did I miss something? I've been looking for a spectrum analyzer in Sonar Professional.  It helps me to view the wave form when using the equalizer.  Is this even available?

If have older versions installed I think even if they did not include the actual Freq Analyst you shoudl be able to do a scan or FX browser refresh and it'll show up.
 
It would be a shame if they removed it though because as awesome as the QC flyout analyser is the Freq Analyst could do crazy stuff like write automation and it had those reference lines you could enable to check your frequency curve across the spectrum to make sure nothing was sticking out in the wrong place.

 
Never used the one offered with Sonar, but here's a popular free one from Voxengo:

IIRC, Sonar PRO has the flyout EQ but not the flyout spectrum analyzer if you are referring to the pro-ch.
I still have the Cakewalk Analyst from previous versions.
Go to Voxengo.com and get their free version of Span. It is pretty good.
 

MFreeEffectsBundle has both a free standing spectrum analyzer plug-ins and an EQ with a built-in spectrum analyzer.

I think this is one of those scenarios where if they removed the feature for the sake of stability and/or modernizing the program it would be nice if paid users had the option to download legacy tools from their accounts. Just put a big bad ole warning alongside it stating they are outdated and may cause performance issues.
 
Like the the VC-64 and some of the old 32 bit thingies. If Cake still owns the rights to these tools I think it would be a nice option to have. It certianly comes up enough here on the forum.

Microapp has it correct.  No frequency analyzer in Professional.
 
Before quad curve EQ, I used Voxengo Span so consider this another endorsement for that bit of kit.

I was referring to (and thought the OP was) this....
 

 
but I may be mistaken.

This is a great idea.

I agree that Voxengo Span is the way to go! And it's free!
