RF enclosures require ventilation when large amounts of heat are generated in testing. Forced cooling is also required for Device Under Test (DUT) in some applications. As the frequency increases, wavelength becomes smaller. In high frequencies ...
Radio frequency shielding is an approach to avoid undesired energy being coupled into equipment under test. The ability of an enclosure to avoid undesired RF fields to couple to the device under test is known as its Shielding Effectiveness (SE)...
Process automation and related IIoT applications require advanced wireless network technologies. While wireless Supervisory Control and Data Acquisition (SCADA) systems have been around for a long time, advanced process automation places higher ...
Today, public transportation agencies face a unique set of challenges. They are being asked to do more: serve a growing ridership, improve system-wide efficiency and safety, and reduce operating costs – with increasingly limited resources...
A tier-1 carrier detected significant interference in a sector of its 4G LTE wireless network. Internal reports showed an increased noise floor on the uplink band. UL interference causes significantly lower throughput, jeopardizing Quality of Service
With applications including social media, high definition video streaming, mobile banking, and full-featured web browsing, broadband cellular applications provide exciting opportunities for consumers and network operators alike....
TD-LTE is the 4G upgrade path for operators with unpaired spectrum, bringing increased capacity, flexibility, and data throughput rates to markets around the world. In most respects, TD-LTE works the same as LTE FDD. However, where FDD transmits ....
The phase noise specification of an RF signal generator is important for several measurements in the receiver. We will focus on receiver selectivity, adjacent channel measurements, and on-channel measurement such as In-Phase (AM) or Quadrature ...
The Aeroflex 3550 Radio Test System now includes new methods for more accurately measuring power, distance to fault (DTF), return loss (RL), and voltage standing wave ratio (VSWR)....
The Viavi Signaling Analyzer family maximizes the effectiveness of engineers who develop, plan, install, optimize, and troubleshoot complex mobile networks. This robust product family delivers on the needs of higher intelligence and performance ...
Testing and verification of radio frequency (RF) alignment parameters is required to maximize and deliver the high performance that digital technology provides. Improper alignment causes degraded digital modulation accuracy ....
This application is self contained within the 3920 Digital radio Test Set and automatically performs the test functions as prescribed by the EIA/TIA-603 standards for testing any FM Land Mobile Radio.
