A key measurement in the development
of devices and systems is its noise
figure. The overall noise figure of a
system is one of the limiting factors
in its performance. Making noise
figure measurements can be a tedious
manual process. But with Agilent’s
noise figure measurement systems,
these measurements can be fast and
easy with accurate results. Meet many
of your measurement needs with
a one-analyzer solution from Agilent.
• Perform system calibration easily
and quickly.
• Analyze the device noise figure in
several different formats.
• Characterize the noise figure of
frequency conversion devices.
• Easily calculate measurement
uncertainty.
The Agilent PSA Series offers high
performance spectrum analysis up to
50 GHz with powerful one-button
measurements, a versatile feature set,
and a leading-edge combination of
flexibility, speed, accuracy and
dynamic range. Expand the PSA to
include noise figure measurements
with the noise figure measurements
personality (Option 219).
The noise figure measurements
personality provides noise figure and
gain measurements over the frequen-
cy range of the PSA with specified
measurements over the 10 MHz to
3 GHz range.
The technical overview includes:
• measurement details
• demonstrations
• PSA Series key specifications for
the noise figure personality
• ordering information
• related literature
All demonstrations use the Agilent
346C noise source, mixer, amplifier
and 70 MHz band pass filter. The
keystrokes surrounded by [] indicate
hard keys and while key names
surrounded by {} indicate soft keys
located on the right edge of the
display.
Noise figure measurements:
• entering ENR values
• calibration
• noise figure and gain
• using display features
• measurement uncertainty calculator
• mixer as the DUT
• mixer as part of system
