Can an oscilloscope be made to do spectrum analysis?

[Edward A. Dauer]

I just purchased a DS1102E Rigol Œscope and wondered if those who use this
or similar equipment have been able to use it as a spectrum
analyzer (to draw amplitude vs frequency rather than amplitude vs time.)
The Rigol has an external trigger channel, which if I remember correctly
from the last time I owned a Œscope in 1959 or so, is where a horizontal
sweep could be applied.  The manual ­ translated into English by someone
whose English wasn¹t all that good ­ is silent on the subject.  Actually I
haven¹t read it all yet but I have done a word search for everything I
could think of, with no luck.   Is it possible to do this?  If so, any
suggestions about what additional
toys I would need to buy?

Press the "Math" button and look for "FFT".
