Are you asking how to use the equipment, or what equipment to get? Equipment wise, a Radio Shack analog or digital meter, a Stereophile test disc with 1/3 octave test ones using pink noise (which I prefer over pure frequency tones), a conversion list of low frequencies in the RS meter - the actual frequencies at 20hz are much higher than recorded but by 100 hz the RS meter is fairly correct) and if your going to play with speaker set up, some graphpaper so you can chart the FR from tests in a graphic way, and see from this how different speaker and listening positions change as you move things about. If you have any questions about its actual use, just ask.
