requirements of relevant standards regardless of what market they are working in. "We will also ensure that the
equipment provided will be acceptable
across multimarket testing agencies, so
the equipment can be bought once and
used for multiple tests," he added.
When asked what features customers
seek in EMC test equipment, Landers
cited reliability. "A test agency or laboratory needs to know for certain that
their equipment, on any given day, can
be placed into a test setup and work the
first time, every time," he said. "AR provides this level of quality and reliability
for each product."
Landers also pointed out, "Customers
are looking for total turnkey solutions,
where we not only provide the amplifiers, but the antennas, cables, racks, field
probes, etc., all within a single system to
test specific or multiple standards."
Jeff Hu, product manager at Keysight
Technologies, said the company addresses
full-compliance test with products such
as the N9048B PXE EMI receiver, which
offers 1-Hz to 44-GHz frequency coverage,
and is fully compliant with CISPR 16-11:2019 and MIL-STD-461G. Hu explained
the instrument offers a "...superior 'Time
Domain Scan' and even faster 'Accelerated
Time Domain Scan' measurement speed,
with a time-domain scan that supports up
to a 350-MHz FFT acquisition bandwidth.
He also described an "...accelerated timedomain scan example with a scan time
of 5.8 seconds vs. multiple hours using
a conventional stepped-scan approach
(test conditions: CISPR band C/D, 30 to
1,000 MHz; RBW = 120 kHz; QP + CISPRaverage detector; dwell Time = 1 s)."
Hu described a "Real Time Scan"
troubleshooting tool, offering up to 350
MHz of bandwidth for gapless real-time
signal capture and analysis. The tool allows customers to measure signals with
CISPR-compliant quasi-peak, EMI average, and peak detectors simultaneously,
gaining a better understanding of signals
by displaying them in three windows -
frequency domain, time domain, and
spectrogram. Customers can also play
back and view signals captured in up to
12,000 time slices (for example, 12,000 s
recorded time if dwell time is 1 s), and Hu

added that data can also be exported for
post-processing analysis
"As customers (automotive, consumer,
communications, medical, etc.) designing electronic devices race to market,
they will need better, faster EMC compliance testing of new components, key
subassemblies, and whole systems," Hu
said. "For EMC labs, this means greater
demand for more testing and troubleshooting in less time, sometimes on short
notice, as developers rush to meet looming deadlines. Day to day, the throughput
rate of the main test chamber has a direct
effect on two key metrics: revenue and
customer satisfaction. If demand grows
beyond the capacity as we're seeing now,
then the test lab can lose revenue and
force customers to go elsewhere. During
troubleshooting, delays in assessing failures and suggesting fixes can frustrate
impatient customers."

Hu continued, "Enhancing the lab's
success starts with a compliant EMI
receiver that accelerates testing and improves troubleshooting. Equipped with
Time Domain Scan, Accelerated Time
Domain Scan, and Real Time Scan capabilities, the Keysight N9048B PXE EMI
receiver will accelerate throughput during
compliance testing and enhance the ability to catch suspect signals sooner during
troubleshooting." He added that the PXE
supports many EMC software tools (such
as TILE!, Nexio, and Toyo), which can leverage the PXE's speed during automated
testing. The solution also provides capabilities tuned to measurements, reporting, documentation, and more.
