spectrum analyzer questions

[Opcom]

calling all test gurus,

I am in need of a 'professional' spectrum analyzer covering near-zero Hz to at least 100MHz, preferably 1G or better. The big deal is the low end, and most seem to stop at a few MHz, although one stops at 9KHz. That is not low enough for this work. We will look at signals as low as 3KHz, and want to see what is a little below as well.

Does anyone know of such an instrument that can be bought from a commercial dealer?

PC based/USB, etc. is acceptable

has to be calibrated in dBv, dBm, and frequency

must be able to distinguish between signals less than 100Hz apart or better.

has to be "portable", so 20 lbs is OK, 40 is pushing it. "luggable" is a better term.

tracking generator a plus.

thanks,
PJ

Seems like the signal hound is a great measurement tool, and is in the price range of a Perseus or equivalent, but how does the receiver function compare for listening use?

I have used one briefly in the past but did not get to try it as a receiver or on the HF bands. I will have another chance in the near future to evaluate it more extensively. I'll let you know.

Signalhound looks pretty good, and is not expensive.
