You need not spend a ton of money to get a feature-packed oscilloscope, provided you don’t need high bandwidth. While the oscilloscope works well, the free software needs help. After seeing the Uni-Trend (Uni-T) UTG962E Function/Arbitrary Waveform Generator ($182), we at EE World bought one and, at the same time, ordered a UPO1202 200 MHz […]

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 […]
Engineers use AI/ML to improve test
Engineers can use AI/ML to reduce test development time, analyze test data from manufacturing, automate visual inspection and calibration, and identify counterfeit components. Here’s how some do it. Testing takes too much time; just ask any engineering or production manager. Shortening test-development time can reduce time to market. Shortening production test time lowers manufacturing costs. […]
Tryout: Uni-T UTG962E Function/Arbitrary Waveform Generator
This waveform generator is small enough to fit on any bench and packs many useful features so long as you operate it from the physical or virtual front panel. The software, however, needs work. Walking the exhibit floor at IMS 2024, I passed by the Uni-Trend (Uni-T) booth where the UTG962E Function/Arbitrary Waveform Generator caught […]
USB DAQ system reaches 20-bit resolution
The mioDAQ from NI has two 20-bit and two 16-bit flavors. Analog outputs come with two or four, with 16-bit DIO and counters. USB data-acquisition (DAQ) devices have been on the market for many years and come in many varieties. What makes the mioDAQ series from NI different is its 20-bit vertical resolution on two […]
Video: How should 5G, 6G evolve?
EE World spoke with Matsing’s Manish Matta and Keysight’s Roger Nichols on how 5G is evolving into business use cases and where 6G could play a role.
IMS 2024 roundup: RF components
Washington, DC — The International Microwave Symposium (IMS), which took place here in June 2024, featured a wide array of RF, microwave, and mmWave components. These components range from passive connectors and waveguides to amplifiers, switches, filters, and data converters. In general, these components make their way into military communications systems or commercial wireless networks.…
IMS 2024 roundup: test equipment
Washington, DC — The 2024 International Microwave Symposium took place here in June at the Walter E. Washington Convention Center. As always, RF/microwave/mmWave test equipment was all over the exhibit hall. Frequency-domain test equipment — spectrum analyzers, vector network analyzers, power meters, and signal generators — were, of course, dominant. Other equipment, such as oscilloscopes […]
OFC 2024: Network equipment
The infrastructure of data communications networks needs lots of fiber, semiconductors, and network equipment to bring data to the masses. Optical data networks form the backbone of today’s communications. Data centers, which seem to dominate any discussion of digital communications, depend heavily on fiber-optic connections from a few meters to many kilometers. Getting those bits…
OFC 2024: Test equipment
Before those 800G links can operate, they need testing. San Diego — The 2024 Optical Fiber Communications Conference (OFC) took place here from March 25 to 28. While companies highlighting their optical transceiver modules, semiconductors, and network equipment all touted how they support AI and data centers, none of that happens without test equipment. Optical […]
