Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces...

To ensure the stability of voltage regulators and switchedmode power supplies, the control loop behavior must be measured and characterized. A well compensating voltage controller enables stable output voltages and reduces the influence of load changes and supply voltage variations. The quality of this control circuit...
Weatherproofing options for coaxial connections at cell sites have changed and expanded along with the cell sites themselves. Today’s more complex cell site designs demand a new type of weatherproofing solution to protect vulnerable connection points at the antenna and the remote radio unit (RRU).

The demands for faster wireless access and lower latency are continuously increasing. To meet these demands and to drive new use cases, regulatory bodies around the world open up spectrum in the 6 GHz band for unlicensed use. This new spectrum allows the Wi-Fi 6 standard, IEEE 802.11ax, to unfold its full power. It will...

True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads. Decibels are found everywhere, including power levels, voltages, reflection coefficients, noise figures, field...

Modern vehicles can contain over 100 ECUs controlling everything from the drivetrain to the ADAS systems. Each ECU needs to be tested individually as well as in conjunction with other components.
This white paper discusses the five main tester design challenges and five common approaches to ECU production test to...
The audio market for wireless Bluetooth headsets is growing rapidly. People have gotten used to wireless audio systems, and the mobile phone industry is pushing towards a world without audio connectors and cables. Most of the average users who think about Bluetooth audio picture clumsy over-ear headsets with very little...
Adding security to a device costs extra money, time, power consumption and makes everything worse. The only reason for adding security to a device is the need to improve marketing – security components help to sell more products. To participate in the evolution of Industry 4.0, the Internet of Things and cloud technologies...
This application note created by the Test and measurement specialist Rohde & Schwarz and the University of New Hampshire Interoperability Laboratory (UNH-IOL) describes methods of implementation (MOI) for precise, fast and error-free compliance testing of high-speed cables and backplanes according to InfiniBand standards...
