manufacturing and maintenance needs.
"In this way, we optimize our operational
scenario (that is, size, weight, and power)
for the depot setting so maintenance can
deploy closer to the military assets they
serve," Vondran said. "Our engineer-toengineer collaborative culture is key for
developing a reliable and sustainable
platform."

EW hardware and software
EW has been one focus of Keysight
Technologies Inc., which recently announced new EW threat-simulation solutions, including software and hardware,
that generate modern EW RF environments to enable engineers to efficiently
test their EW systems. The new solutions
include two commercial off-the-shelf
(COTS) products: Simulation View software, which enables the development, integration, and test of sophisticated EW
systems with real-time RF modeling and
dynamic high-fidelity visualization, and
UXG Agile Vector Adapters, now available in 20-GHz, 40-GHz, and 44-GHz
versions, which combine fast frequency,
phase-and-amplitude, and time-delay
switching speeds with real-time pulse
descriptor word (PDW) streaming. (PDW
is the data used for creating radar signals.)
Keysight's products, and the support
of open interfaces and architecture, offer customers EW threat-simulation solutions ranging from benchtop testing to
full-scale threat simulation. Scalability,
coupled with the ability to reconfigure
the system to utilize RF test assets effectively, delivers a modernized EW test and
evaluation solution.

"Keysight understands that our customers need solutions that can maintain
pace with the accelerating evolution of
the EW threat environment," said Greg
Patschke, general manager of Keysight's
Information Warfare Group, in a press release. "We will continue to partner with
our customers to create and deliver rapidly adaptable solutions that help them
advance their labs to the next level of
testing."
The open architecture of Keysight's
EW threat simulation solutions enables
customers to create scenarios with a
variety of software tools, often utilizing
a customer's existing threat databases.
Customers can also choose the software
tool that best fits their EW test needs for
pre-scripted or dynamic real-time threat
generation, or both.

Instruments and data acquisition
According to Jason Chonko, applications marketing manager at SIGLENT
Technologies North America, the company's products can support aircraft
electronic systems as well as basic circuit
design and troubleshooting. "Our bench
and handheld oscilloscopes are ideal for
product development as well as on-board
troubleshooting of electronic systems
throughout the airframe," he said. "For
communications, satellite, and radar applications, our growing list of RF products
delivers high performance and capabilities. The SIGLENT spectrum analyzers,
RF sources, arbitrary generators, and
vector network analyzers provide deep
insight into component and systemlevel performance. Testing and monitoring transmitters, receivers, as well as
troubleshooting and characterization of
components, adapters, and cabling are

part of our list of strengths. The new 3.2GHz VNA-equipped SVA1032X analyzers
are easy to transport and can be used
throughout the aircraft for in-situ testing
of receivers as well as RF components."
According to David J. Rodgers, senior
program manager for SAN, Ethernet, and
Fibre Channel technologies at Teledyne
LeCroy, "Our products will be used for
evaluation and verification of wired,
fibre-interconnect communications,
focused on, but not limited to, ensuring
fly-by-wire messaging is accurate, timely,
and complete." Specific products include
the SierraNet M168 Fibre Channel and
Ethernet test platform, which includes
data capture, analysis, and manipulation
routines. "SierraNet enables test/validation
engineers to observe and modify the physical interface and associated data frames
used in mission-critical avionics and communications systems," Rodgers said.
