I have a need for a spectrum analyzer that is capable of resolving 120dB at 1MHz. It should also cover the audible range, i.e. 20-20000Hz. A built in signal generator would be nice to have but not a must. Any suggestions for a good name brand piece of equipment?

Hi
professional Spectrum analyzer cost lot of money
From your post I can learn that you mostly needed it for audio design (low noise) and - 120Db is a very sensitive device at this frequency's
Whether you need it for work I recommend you buying one from Keysize(agilent) for this frequency range or find refurbished or used one in Ebay
There is lot to offer not sure you find one with 120db in 1Mhz range

If you are looking for a brand like Tektronix or Agilend , then prepare to spend lots of $. If you are interested in just measuring with a good tool (but without a TEK or Agilent sticker on it) then get a Rigol. Have a look at batronix.com, they have a lot of good tools you can get for a reasonable price.

a used one on ebay might be a good bet as well.

I finally bought an HP 3577B and it seems to have the required resolution and accuracy.

I have a ESA L1500A going in to ebay next week for ~$1000USD if I'm lucky, maybe lower if not.

1MHz to 1.5GHz, no generator installed, great condition, with some minor scratches.

If anyone interested let me know, maybe we can get some donation going to Sonsivri as well help me recovering from my Oscilloscope purchase..

You may want to look into these:

I forgot I have 2 of the NF5035's and am planning to sell one.  If you're interested, please pm me and I'll send you the options on it.  Thanks.

Maybe the Signalhoud USB-SA44B?
A very nice device, works as advertised.
And an impressive measurement range that goes down to 1Hz, which nowadays is something not so usual.

Rigol's DS815 is a good entry level SA for EMI prescans. Its AVG detector is a crap but if scanning with low VBW one can get realistic AVG measurements. The QP detector seems to be working fine. The price is just a fraction of Agilent's, so good value for money.
