77jovian,
There are several options. Room EQ Wizard (PC) or Fuzzmeasure (MAC) are possible software options. Since you need a microphone and good ones are powered by phantom then you may as well get a E-MU 0202 or some other similar USB box that does A to D and D to A as well as powering a microphone. Finally a microphone and a stand. A cheap but good microphone is the Behringer ECM8000 but there are several other options. I like Fuzzmeasure because it uses frequency sweeps, which has significant advantages in being able to perform more powerful analysis. (Mathematically speaking a frequency sweep can be auto convolved to get a dirac function which is like an impulse response. The only complication of this more powerful analysis technique is you need to know a bit about appropriate 'windowing' so as to ensure you interpret the data properly and do not get hung up on window artifacts - in general the software and help files are easy to follow and their is plenty of information about fourier transforms and spectral analysis on the web)
