	 Increasing complexity and the need
for higher frequencies and bandwidths, multiple channels, low-power
operation, and space constraints are placing considerable demands on RF/microwave test equipment. Solutions extend
from simulation software to bench, modular, and portable instruments to complete systems, for applications from R&D
to compliance test and field service.
"The RF/Microwave test field is witnessing a profound change related to
the diffusion of technologies using RF
signals (and, in the most advanced applications millimeter-wave signals) to
communicate, transfer, and exchange

information," according to an email
message from Keysight Technologies. In
the last few months, the company has introduced several hardware and software
solutions.
"On the software side, Keysight's
PathWave integrated software suite
plays a critical role in 5G and mmWave
design, verification, and test methodologies," the company said. "PathWave
software streamlines the entire workflow
from system-level modeling to RF/microwave circuit co-simulation and analysis.
Companies like Nokia Bell Labs rely on
PathWave and the entire Keysight ecosystem to gain the valuable engineering

insights they need to push wireless technology to the next level. Keysight is also
collaborating with Nokia on a new software approach that leverages artificial intelligence and advanced data analytics in
the company's 5G base station manufacturing processes, significantly improving
test efficiency."
On the hardware side, Keysight in 2019
introduced what it calls the first singlebox multichannel solution for wideband
mmWave measurements. "Based on the
UXR-Series of oscilloscopes, it delivers
fast, affordable, coherent analysis for
wideband measurements up to 110 GHz.
This solution accelerates the development
