In case your mouse is misfiring, some choice quotes:

www.hameg.com: "Due to the superhet receiver principle, the logarithmic analysis and display of data, the spectrum analyser has a thousandfold higher sensitivity and a higher dynamic range (› 80dB) compared to an oscilloscope."

www.tutorialsweb.com: "Normally, Oscilloscope can not measure very low voltage levels (say, -100dBm) and are intended for low frequency, high amplitude measurements. A spectrum analyzer can easily measure very low amplitudes (as low as -120dBm), and high frequencies (as high as 150GHz)."

And so on...

Neil
