Hello,
Since money doesn't grow on tree 🙁 (well except for certain variety😉 )and since a spectrum analyzer cost more than my car
, what I would like to know is there a way to conver an oscilloscope into a spectrum analyzer? Is there a gadget/equipment I can use to conver an o-scope into a spectrum analyzer?🙂
Thanks!

What sort of bandwidth are you looking for? Two cheap solutions include PC soundcard plus software or something like an HP3581A wave analyzer hooked to a chart recorder or PC chart recorder analog.
BTW, I see from your avatar that you've met my ex-wife.

A good sound card (such as the Audigy 2, the value one is OK) plus Audiotester

will set you back by about $100, and do a lot up to some 45KHz.

No, not very easily but you can get one of the Tektronix 1000 series scopes with FFT for less than $1500. It does not have the greatest dynamic range but it may be sufficient.
i have one of those TEK scopes with FFT -- they are great for looking for power supply problems -- but a dedicated spectrum analyzer or sound card is probably a better solution for the questioner --
SY points out the HP3581 -- I think that this is one of the best values for any DIY'r -- note that you can get a serial or USB port data-loggers from Jameco and elsewher which will dump your results right into Excel -- the HP3581 has really excellent dynamic range -- and you aren't going to see digital artifacts in the output. The HP3581 is like buying a Mercedes S600 Pullman for the price of a Ford Taurus.

As inexpensive as 3581s are, I'd recommend having that in addition to any digital stuff- it provides a reality check and is a darn nice AC voltmeter for level-setting.
I use an EMU1212 sound card with Rightmark Audio and SmartLive software. I also have a tek TDS220 and a TEK2235. I use the soundcard set up more than the scopes.
