VNA Impedance Measurement for Power Distribution Networks
Indianapolis, January 15, 2019 -
Mountain Technologies' Steve Sandler will present a webinar on January 22, at
11 am EST, about
VNA Impedance Measurement for Power Distribution
Networks. Almost all modern circuits are sensitive to power quality, which to
a large extent is a measurement of the power rail impedance. This is because flat
impedance power rails result in much lower noise than power rails that aren't flat.
In RF circuits the peaks generally result in increased phase noise, while in digital
circuits the issues are related to the allowed voltage window for the ASICs. In
high-speed transceivers, these peaks result in jitter, which is also related to
phase noise. In analog circuits, the peaks can result in increased noise density
and in analog to digital converters the peaks result in spurious responses. The
power rail impedance is typically controlled by the careful selection of bulk aluminum
or tantalum capacitors, ceramic decoupling capacitors, inductors, and ferrite beads.
The instrument of choice for these impedance measurements is a vector network
analyzer and the most common and highest accuracy measurement is the 2-port shunt
through technique, using a 2-port VNA. The VNA offers the excellent dynamic range
and also wide bandwidth.
About Copper Mountain Technologies
Mountain Technologies develops innovative RF test and measurement solutions
for engineers all over the world. The company's headquarters is in Indianapolis
with sales offices in Singapore and Miami. The company pioneered metrology-grade
USB VNAs in 2011 and continues to push for innovation and change in the industry
to ensure engineers have access to the best technology. CMT achieved ISO 9001:2015
certification in 2019. The calibration lab in the USA is accredited in accordance
with the recognized international standard ISO/IEC 17025 (2017) and meets all requirements
of ANSI/NCSL Z540-1994-1. All CMT VNAs include application and automation support,
and years of our engineering expertise at your disposal.
Copper Mountain Technologies provides a broad range of USB vector network analyzers,
calibration kits, and accessories for 50 Ohm and 75 Ohm impedance. CMT VNAs are
used for RF and Microwave applications from 9 kHz to 110 GHz by engineers in industries
like defense, automotive, materials measurement, medical, broadcasting, and telecommunications.
Copper Mountain Technologies' VNAs include an RF measurement module and a software
application which runs on any Windows PC, laptop or tablet, connecting to the measurement
hardware via USB interface. The user can take advantage of the latest OS, processing
power, larger display, and reliable performance of an external PC, as well as lower
total cost of ownership and simplified maintenance of the analyzer. The result is
a faster, more effective test process that fits into the modern workspace in lab,
production, field and secure testing environments. This creative approach made Copper
Mountain Technologies a leader in the industry and earned them both the 2015 Frost &
Sullivan Global Leadership in Innovation Award and the 2017 Product Leadership Award.
