1-2. The Hewlett-Packard Model 3580A Spectrum
Ana-
lyzer
is
a low frequency instrument that has been optimized
for
use
in the 5
Hz
to 50
kHz
range. The 3580A functions
as
a signal analyzer or
as
a network analyzer.
When
used
as
a signal analyzer, the 3580A provides a graphical display
of
the spectral components
of
an
input signal.
When
used
as
a
network analyzer, the 3580A plots the amplitude
vs.
frequency characteristics
of
2-port networks such
as
ampli-
fiers, attenuators and filters.
1-3. The major features
of
the 3580A include a digitally
stored display, adaptive sweep, six selectable bandwidths
(1
Hz - 300 Hz), 30 nV sensitivity and 80
dB
dynamic
range. These standard features, along with optional bal-
anced inputs and
an
internal rechargeable battery pack,
make the 3580A ideally suited for communications,
geo-
physical, oceanography and metrology applications.
