The UDS series from Rohde & Schwarz provides the company with a significant upgrade and place it against top competitors. Digital multimeters (DMMs) are a measurement staple, sitting alongside oscilloscopes, power supplies, and waveform generators on just about every engineer’s bench. You may not think of Rohde & Schwarz as a major competitor in the […]

Demonstration shows 5G handset communicating through satellites
Five organisations, the Singapore University of Technology and Design (SUTD), SKY Perfect JSAT (JSAT), TMY Technology, Inc. (TMYTEK), Rohde & Schwarz, and VIAVI Solutions (VIAVI)[1], have jointly developed a new 5G non-terrestrial network (NTN) satellite technology to advance mobile connectivity in remote locations. The research team conducted a live demonstration at the World Expo 2025…
APEC 2025 test equipment: oscilloscopes and probes
Oscilloscopes and probes play a vital role for engineers designing and testing power electronics. Delivering electrical power to analog and digital circuits and systems is more than just DC measurements. That’s because nearly all power-converter circuits use switching techniques to maximize efficiency. Silicon carbide (SiC and gallium nitride (GaN) transistors, with their higher voltage and […]
Review: Tekbox TBCG4 harmonic comb generator
The Tekbox TBCG4 harmonic comb generator produces a wide range of known frequencies for EMC immunity testing and routine checking of EMC chambers. I’ve used harmonic comb generators for decades in various applications, including antenna measurements, cable resonance measurements, and shielding-effectiveness testing. I also find them useful for checking the daily consistency of test chambers […]
Free and low-cost online EE tools aid in design
Downloadable and online free and low-cost EE tools help engineers design and analyze circuits. The internet is full of EE tools from equipment manufacturers, semiconductor manufacturers, independent EEs and hobbyists. Some are web-based that you can use with just a browser. Some you need to download and install on your PC while others you install […]
How to determine noise figure: part 4
Two incompatible definitions of noise factor can lead to confusion, which you can alleviate by understanding where the differences lie.
IEEE Phased Array 2024: what we saw
The IEEE Phased Array conference occurred in Boston on October 15-17, 2024. This specialized conference had a small exhibit floor. Here is some of what was on display. Boston — The 2024 IEEE International Symposium on Phased Array Systems & Technology moved into the city after taking place in a suburban Boston hotel for several…
Should I use a spectrum analyzer, signal analyzer, or vector network analyzer? part 4
A vector network analyzer can fully characterize components by deriving their scattering parameters. In earlier parts of this series, we looked at analog spectrum analyzers (part 1 and part 2) and vector signal analyzers (part 3), both of which monitor unknown signals, whether emanating from a system, device under test (DUT), or an enemy’s transmitter […]
Viavi, R&S combine to test OpenRAN radios
Rohde & Schwarz (R&S) and VIAVI Solutions Inc. announced an expansion of their partnership delivering state-of-the-art O-RU testing. These solutions are ideally suited to the needs of radio manufacturers planning to bid for the United States Department of Commerce’s National Telecommunications and Information Administration (NTIA) Public Wireless Supply Chain Innovation Fund (PWSCIF) Second Notice of…
How to reduce residual noise in 5G NR EVM measurements
Error vector magnitude (EVM) is the most important figure of merit for signal quality in 5G NR. A new method improves measurement accuracy by reducing noise.
