Sound Spectrum Analyzer (SSA)
There are applications which call for the simultaneous
measurement of both the sound pressure level and the real-
time frequency spectrum. Very often you will wish to
measure the weighted (A, C or Flat) sound pressure level
while simultaneously measuring the unweighted frequency
spectrum.
For these applications, the System 824 provides the SSA
instrument.
