R&S digital multimeters feature 5.5 and 6.5 digits with triple displays

July 3, 2025 By Martin Rowe

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 […]

APEC 2025 test equipment: oscilloscopes and probes

March 26, 2025 By Martin Rowe

oscilloscope and probes in power electronics

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

January 24, 2025 By Kenneth Wyatt

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 […]

Should I use a spectrum analyzer, signal analyzer, or vector network analyzer? part 4

September 3, 2024 By Rick Nelson

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 […]
