SANTA CLARA, Calif. -- November 28, 2012

Agilent Technologies Inc. (NYSE: A) today announced the extension of its
source-corrected noise-figure measurement capability in PNA-X network
analyzers to 43.5 and 50 GHz, while continuing to maintain the highest
noise-figure measurement accuracy in the industry. Built directly into the
Agilent PNA-X, the technique provides a complete single-connection,
multiple-measurement capability for R&D and manufacturing engineers developing
and testing low-noise transistors, amplifiers, frequency converters and
transmit/receive modules.

Accurate noise-figure measurements are required to test devices in
aerospace/defense and wireless communications systems, but can be difficult to
achieve when a traditional noise source cannot directly connect to the device
under test. This scenario creates a number of problems in today’s automated
test, on-wafer, or in-fixture test systems.

Agilent’s source-corrected measurement technique eliminates these problems and
provides a unique single-connection solution for S-parameter and noise-figure
measurements, along with other measurements such as harmonics, compression,
and intermodulation distortion. The use of a single connection for all
measurements speeds up testing, improves throughput in manufacturing, reduces
wear on connectors and probes, and minimizes risk of wafer damage.

Agilent’s new 50-GHz noise hardware features a built-in low-noise receiver and
impedance tuner that simplify measurement setups and enable fully
vector-noise-corrected measurements. Unlike other noise-figure solutions,
Agilent’s PNA-X network analyzers combine S-parameter vector-error correction
and an impedance tuner to fully remove the effects of imperfect system source
match. Agilent’s solution also corrects for the interaction between the output
match of the device under test and the noise figure of the internal receiver.

These advanced error-correction methods result in accuracy that is superior to
the Y-factor method and other simpler forms of the cold-source method. In
addition, users can now conveniently choose to use either a power meter or a
noise source to calibrate the noise receiver.

The 50-GHz noise hardware is also available in 67-GHz PNA-X models. To measure
noise figure between 50 and 67 GHz, engineers can use the standard network
analyzer receivers and an external ECal in conjunction with an external LNA
and high-pass or band-pass filter.

“Agilent’s high-performance, network-analyzer-based noise figure measurement
technique is the most accurate available today,” said Gregg Peters, vice
president of Agilent’s Component Test Division. “Extending its reach to 43.5
and 50 GHz opens the technique up to new applications, while further
reinforcing our commitment to providing the widest range of
noise-figure-measurement choices to meet our customers’ ever-changing

The Agilent PNA-X is part of the PNA family of network analyzers, which
includes the PNA-L, PNA and PNA-X Series, covering frequencies from 300 kHz to
1.05 THz. The PNA-X provides complete linear and nonlinear component
characterization in a single instrument with a single connection. The entire
PNA family offers advanced connectivity via LAN, USB and GPIB; an easy-to-use
open architecture based on the Microsoft Windows® operating system; and an
extensive embedded help system. The PNA family’s CPU and operating system can
be upgraded as technologies evolve.
