Frequency Parameters
Carrier Frequency
is the
fundamental (center) frequency
of
the device you
are measuring.
The HP
3048A uses
the
Carrier Frequency entry
to:
• Label
the
Carrier Frequency
on the
Results Graph.
• Calculate Sigma vs.
Tau and
S
y
(f).
NOTE
When loading
a
Result File
for
calculating Sigma
vs. Tau,
the carrier frequency used
for the
measurement must
be
entered
in the
Instrument Parameters display
in
order
to
compute accurate values.
