Unfortunately, spectrum analyzers don't do well in
this application.  The various partials change their
relative strengths as time passes and one can only get
a snapshot in time of what the harmonic content was at
the instant of the measurement.  In other words, you
get different results as the tone decays, depending on
when you measure.  Looking in the "time domain" (with
an oscilloscope) holds more promise for identifying
the differences among the various instruments.
